Online Platform Agreements

1. Introduction

Online Platform Agreements are contractual arrangements governing the relationship between a digital platform and its users, sellers, service providers, advertisers, developers, or other participants. They include terms of service, user agreements, seller agreements, marketplace agreements, app-store agreements, payment terms, developer agreements, advertising agreements, data-processing terms, and platform participation contracts.

From a competition-law perspective, these agreements are important because a platform may control access to a significant digital ecosystem. Contractual provisions that appear commercially ordinary can potentially restrict competition through exclusivity, MFN clauses, tying, self-preferencing, discriminatory access, restrictions on multi-homing, data restrictions, interoperability limitations, or excessive switching costs.

2. Meaning and Nature

An online platform agreement generally establishes:

1. Access rights – who may use the platform.
2. Commercial terms – commissions, fees and payment arrangements.
3. Ranking and visibility – how products or services are displayed.
4. Data rights – collection, processing and use of platform data.
5. Interoperability – whether third-party services can connect to the platform.
6. Exclusivity – whether participants may use competing platforms.
7. Advertising arrangements – placement and targeting of advertisements.
8. Dispute resolution – jurisdiction, arbitration and governing law.
9. Suspension or termination – circumstances in which accounts may be restricted.
10. Intellectual-property rights – licences concerning content, software and trademarks.

The competition-law significance depends not merely on the wording of the agreement but also on market power, market structure, duration, actual commercial effects and the availability of alternatives.

3. Competition-Law Framework

Online platform agreements can potentially raise issues under several competition-law provisions.

A. Anti-competitive agreements

Agreements between undertakings may restrict competition through:

• price fixing;
• market allocation;
• output restrictions;
• resale-price restrictions;
• customer allocation;
• collective exclusivity;
• information exchange.

B. Vertical restraints

Platform agreements frequently constitute vertical arrangements, such as:

Platform → Seller → Consumer

or

App-store operator → Developer → Consumer.

Potential restrictions include:

• exclusive dealing;
• territorial restrictions;
• resale-price maintenance;
• tying;
• MFN clauses;
• restrictions on alternative sales channels.

C. Abuse of dominance

Where a platform possesses substantial market power, contractual provisions may constitute abusive conduct if they:

• exclude competitors;
• discriminate between trading partners;
• impose unfair conditions;
• deny access to essential inputs;
• leverage dominance into adjacent markets.

D. Merger-related concerns

Platform agreements may also be relevant to digital mergers where contractual arrangements provide the acquiring firm with:

• exclusive access to data;
• control over distribution;
• long-term customer relationships;
• interoperability restrictions;
• access to strategic infrastructure.

4. Major Competition Concerns

A. Exclusivity

A platform may require sellers or service providers to deal exclusively with it.

Example

A dominant marketplace provides better search ranking to sellers who agree not to list products on competing platforms.

Potential concerns include:

• foreclosure of rival platforms;
• reduced multi-homing;
• increased entry barriers;
• reduced consumer choice.

However, exclusivity does not automatically violate competition law. Its significance depends on factors such as market power, duration, coverage and foreclosure effects.

B. Most-Favoured-Nation Clauses

An online platform may require sellers not to offer lower prices on competing platforms.

These clauses are commonly called MFN or parity clauses.

Broad MFN

The seller cannot offer a lower price anywhere else.

Narrow MFN

The seller cannot offer a lower price on its own website but may offer different prices through other platforms.

Competition authorities have examined whether such provisions reduce:

• price competition;
• platform entry;
• commission competition;
• incentives to establish competing marketplaces.

5. Platform Commission Agreements

Platforms commonly charge:

• transaction commissions;
• listing fees;
• subscription charges;
• payment-processing fees;
• advertising charges;
• data or API fees.

A high commission is not necessarily an antitrust violation.

However, where a dominant platform imposes contractual conditions that competitors cannot reasonably avoid, issues may arise concerning:

• unfair pricing;
• exclusion;
• tying;
• discriminatory treatment;
• margin squeeze.

6. Self-Preferencing

A platform may operate both:

1. the marketplace; and
2. its own competing products or services.

Its agreement may permit the platform to use information generated by third-party sellers while simultaneously giving its own products preferential treatment.

Potential competition concerns include:

• preferential ranking;
• preferential access to consumer data;
• preferential advertising placement;
• preferential logistics;
• discriminatory commissions;
• reduced visibility for rivals.

The assessment depends on the applicable jurisdiction and evidence of competitive harm.

7. Tying and Bundling

Platform agreements can require users to purchase or use another service.

Examples include:

• mandatory platform payment systems;
• mandatory advertising services;
• compulsory logistics;
• bundled cloud services;
• mandatory identity verification;
• compulsory ancillary software.

Where the platform has market power, tying may potentially extend that power into an adjacent market.

8. Data-Related Contractual Restrictions

Data is frequently an important component of platform competition.

Agreements may determine:

• who owns data;
• who can access transaction data;
• whether sellers can export customer information;
• whether competitors can access APIs;
• whether users can transfer their data;
• whether the platform can combine datasets.

Restrictive data clauses can increase switching costs and make multi-homing more difficult.

9. Interoperability and API Restrictions

Platforms may contractually restrict access to:

• APIs;
• payment interfaces;
• software-development tools;
• authentication systems;
• messaging systems;
• technical documentation.

A dominant platform may face competition-law scrutiny if restrictions prevent competitors from accessing an important technical interface without adequate justification.

10. Account Suspension and Termination

Platform agreements normally give the operator substantial contractual rights to:

• suspend accounts;
• remove listings;
• terminate users;
• restrict advertising;
• disable payment facilities.

From a competition perspective, concerns may arise where a dominant platform selectively applies contractual rules against competing businesses.

Relevant questions include:

1. Are the rules objectively defined?
2. Are they applied consistently?
3. Does the platform discriminate between similarly situated users?
4. Does termination effectively exclude a competitor?
5. Are adequate alternative channels available?

11. Arbitration and Jurisdiction Clauses

Online platform agreements frequently contain:

• arbitration clauses;
• exclusive jurisdiction clauses;
• foreign governing-law clauses;
• class-action waivers;
• online dispute-resolution provisions.

These provisions primarily concern contract and procedural law, but their practical effect can also matter in competition disputes.

A contractual arbitration clause does not necessarily determine whether an underlying competition-law issue is legally arbitrable; that question depends on the applicable jurisdiction.

12. Important Case Laws

1. Ohio v. American Express Co., 585 U.S. 529 (2018)

The U.S. Supreme Court examined contractual anti-steering provisions imposed by American Express on merchants.

The provisions restricted merchants from steering customers toward alternative payment methods.

The Court treated the credit-card market as a two-sided transaction platform, emphasizing the need to consider both sides of the platform when assessing competitive effects.

Significance

The case demonstrates that:

• platform agreements can affect multiple sides of a market;
• contractual restrictions can influence competition between payment platforms;
• market definition is particularly important for two-sided platforms;
• competitive effects cannot necessarily be analysed solely from the perspective of merchants.

2. European Commission v. Google LLC and Alphabet Inc. — Google Shopping (Case AT.39740, 2017)

The European Commission found that Google had abused its dominant position by systematically giving prominent placement to its own comparison-shopping service while demoting competing services.

Although the dispute concerned conduct beyond a conventional bilateral contract, it is highly relevant to platform agreements because platform terms, ranking rules and participation conditions can interact with the platform's control over visibility.

Significance

It illustrates concerns involving:

• platform dominance;
• self-preferencing;
• ranking;
• discriminatory treatment;
• leveraging of platform power.

3. European Commission v. Google Android (Case AT.40099, 2018)

The European Commission examined contractual arrangements involving Google's Android ecosystem, including agreements concerning:

• search and browser applications;
• licensing of Google Play;
• device manufacturers;
• anti-fragmentation requirements.

The Commission concluded that certain contractual arrangements restricted competition.

Significance

The case demonstrates how platform agreements can become competition concerns where contractual restrictions reinforce dominance across interconnected digital markets.

4. Apple — App Store Practices / European Commission proceedings concerning App Store rules

The European Commission's investigations into Apple's App Store practices examined contractual restrictions governing developers' access to customers and payment arrangements.

The issues included restrictions concerning alternative payment mechanisms and communication with users.

Significance

The proceedings demonstrate the importance of:

• app-store contractual terms;
• payment restrictions;
• developer access;
• anti-steering provisions;
• platform gatekeeping.

They also illustrate how contractual arrangements can have competition significance where a platform controls an important distribution channel.

5. United States v. Microsoft Corp., 253 F.3d 34 (D.C. Cir. 2001)

Microsoft entered into numerous contractual arrangements concerning computer manufacturers, Internet access providers and software distribution.

The U.S. Court of Appeals considered whether Microsoft's agreements contributed to exclusion of the competing Netscape browser and thereby maintained Microsoft's operating-system monopoly.

Significance

The case remains important for understanding:

• exclusive agreements;
• distribution restrictions;
• contractual foreclosure;
• leveraging of market power;
• network effects.

It is particularly relevant to modern platform agreements because digital platforms similarly control important distribution channels.

6. Intel Corp. v. European Commission, Case C-413/14 P (2022)

The litigation concerned Intel's arrangements with computer manufacturers and retailer Media-Saturn involving conditional rebates.

The Court of Justice clarified the importance of analysing whether conduct is capable of producing foreclosure effects rather than treating certain rebate arrangements as automatically unlawful.

Significance

The case is useful for analysing platform agreements involving:

• conditional commercial incentives;
• exclusivity;
• rebates;
• foreclosure;
• assessment of actual competitive effects.

7. Booking.com — European competition proceedings concerning hotel MFN clauses

Competition authorities in Europe examined price-parity/MFN clauses used by online hotel-booking platforms.

The central concern was whether contractual provisions restricting hotels from offering different prices through alternative channels could reduce competition between booking platforms.

Significance

These proceedings are particularly relevant to online platform agreements because they demonstrate the competition-law importance of:

• narrow MFNs;
• broad MFNs;
• platform commissions;
• hotel-platform relationships;
• inter-platform competition.

8. Cotton Candy / Google AdSense — Google AdSense proceedings

The European Commission examined contractual restrictions governing Google's search advertising intermediation services.

The arrangements included provisions affecting third-party websites' ability to display competing search advertisements.

Significance

The case illustrates how contractual provisions can be problematic where they:

• restrict rival advertising services;
• prevent multi-homing;
• foreclose competing platforms;
• reinforce an existing dominant position.

13. Indian Competition-Law Perspective

In India, online platform agreements may be examined principally under the Competition Act, 2002, particularly:

• Section 3 – anti-competitive agreements;
• Section 4 – abuse of dominant position;
• Section 5 – combinations;
• Section 19 – investigation by the Competition Commission of India;
• Section 26 – investigation procedure.

The CCI has examined digital-platform relationships involving marketplaces, app ecosystems, online travel, payment systems and other digital markets.

Particular attention may be given to:

Section 3

Potentially restrictive contractual arrangements may include:

• exclusive supply;
• exclusive distribution;
• resale-price restrictions;
• tying;
• refusal-related arrangements;
• MFN clauses.

Section 4

A dominant platform's agreements may raise concerns involving:

• discriminatory conditions;
• unfair conditions;
• denial of market access;
• leveraging;
• exclusionary conduct.

14. Matrimony.com Ltd. v. Google LLC

The CCI proceedings concerning Google examined Google's practices in online search and search advertising.

The case is significant because it demonstrates the application of Indian competition law to a digital ecosystem involving different categories of users and advertisers.

Relevance

It illustrates the importance of:

• platform market power;
• search ranking;
• digital advertising;
• discriminatory treatment;
• access to digital markets.

15. XYZ v. Google LLC — Android Ecosystem Proceedings

The CCI's Android proceedings examined contractual arrangements involving Google and original equipment manufacturers.

The CCI considered several contractual restrictions associated with Google's Android ecosystem and found concerns under Section 4.

Relevance

The proceedings demonstrate how contractual arrangements can be examined collectively where they affect:

• app distribution;
• search;
• browser markets;
• operating systems;
• competing digital services.

16. Key Legal Tests

When analysing an online platform agreement, the following framework is useful.

Step 1 — Identify the parties

Determine whether the agreement involves:

• platform and consumer;
• platform and seller;
• platform and developer;
• platform and advertiser;
• competing platforms.

Step 2 — Identify the relevant market

Consider:

• product/service market;
• geographic market;
• online/offline substitution;
• multi-sided market characteristics.

Step 3 — Determine market power

Relevant factors include:

• market share;
• network effects;
• switching costs;
• user numbers;
• data advantages;
• entry barriers;
• interoperability;
• ecosystem control.

Step 4 — Identify the contractual restriction

Ask whether the agreement contains:

• exclusivity;
• MFN;
• tying;
• bundling;
• non-compete;
• discriminatory access;
• anti-steering;
• data restrictions;
• interoperability restrictions.

Step 5 — Assess foreclosure

Examine whether competitors are actually or potentially prevented from:

• entering;
• expanding;
• accessing users;
• obtaining suppliers;
• obtaining data;
• reaching customers.

Step 6 — Examine efficiencies

Potential justifications may include:

• prevention of free-riding;
• fraud prevention;
• cybersecurity;
• quality control;
• investment incentives;
• consumer protection;
• technical compatibility.

Step 7 — Examine proportionality

Even where a legitimate objective exists, the relevant question may be whether the restriction is necessary and proportionate to achieving that objective.

17. Special Features of Digital Platform Agreements

18. Defences and Legitimate Business Justifications

Not every restrictive term is unlawful.

A platform may legitimately impose contractual requirements for:

• cybersecurity;
• fraud prevention;
• consumer protection;
• quality assurance;
• intellectual-property protection;
• technical compatibility;
• regulatory compliance;
• prevention of counterfeit products;
• protection of confidential information.

The key issue is whether the restriction is competition-neutral or competitively restrictive, and whether its effects are justified by legitimate objectives.

19. Drafting Considerations

A competition-conscious online platform agreement should preferably:

1. clearly define platform rules;
2. avoid unnecessary exclusivity;
3. provide objective access criteria;
4. establish transparent ranking principles;
5. avoid discriminatory application of contractual provisions;
6. define legitimate reasons for suspension;
7. provide appropriate data portability mechanisms;
8. establish reasonable API-access rules;
9. carefully review MFN provisions;
10. avoid unnecessary tying;
11. provide transparent commission structures;
12. include appropriate compliance and review mechanisms.

20. Conclusion

Online Platform Agreements occupy a central position in modern competition law because contractual terms can determine how businesses and consumers access digital ecosystems. The principal competition concerns involve exclusivity, MFN clauses, self-preferencing, tying, anti-steering provisions, discriminatory access, data restrictions, interoperability, commissions and termination rights.

The principal lesson from cases such as American Express, Microsoft, Google Shopping, Google Android, Intel and the Booking.com MFN proceedings is that the legality of a platform agreement cannot ordinarily be determined merely from the existence of a restrictive clause. The analysis generally requires consideration of market power, market structure, network effects, contractual coverage, foreclosure, competitive effects, efficiencies and the availability of alternative channels.
