On 5 January 2026, the competition and consumer practice group, AdLegal, lodged a complaint with the COMESA Competition and Consumer Commission (the“CCCC”) under Regulation 67 of the new COMESA Competition and Consumer Protection Regulations, 2025 (the “Regulations”). This complaint was launched against Meta Platforms Inc and Meta Platforms Ireland Limited, following its 15 October 2025 amendment to WhatsApp User Agreements, which allegedly restricts the manner in which other AI chatbots can use WhatsApp’s application programming interface (“API”).
The User Agreement is a contract entered into between users and WhatsApp that sets out what either party is entitled to do. With WhatsApp alleged to be a preferred, or ‘dominant’, messaging platform throughout the African continent, this purportedly provides both WhatsApp and its parent company, Meta, an unduly strong platform on which to promote its own services.
Meta has been accused of the similar violations by competition authorities elsewhere and faces probes across multiple jurisdictions, including in the European Union and Brazil.
AdLegal’s claim against Meta
AdLegal alleges that Meta currently allows users access to Meta AI directly in WhatsApp chats, further that the API is used to integrate any third-party software, including alternative AI products, which compete directly with Meta AI, such as Grok, Gemini and Open AI’s Chat GPT.
In this regard, AdLegal alleges that:
- Meta’s updated user contract, which restricts the use of this API by competing AI companies, restricts entry of new AI companies into the market, violating Regulation 36(1)(a) of the Regulations;
- this conduct deters and prevents competition in the AI market, which violates Regulation 36(1)(b) of the Regulations.
- the update can foreclose other undertakings from the market that rely on WhatsApp’s platform to provide their AI services to users, violating Regulation 36(1)(c) of the Regulations.
What this means for Meta and for the COMESA market
While the CCCC’s investigation into the alleged conduct remains in its initial stages, the complaint sends a strong message to multinational companies that enforcement and complaints in the COMESA region are to be taken seriously, particularly with the onset of the new Regulations, promulgated in late 2025. The complaint is a signal to multinationals, particularly in digital markets, that compliance with the competition regulations will be enforced, particularly where dominant market positions are alleged to have been abused.
John Oxenham, director at Primerio notes that the complaint marks a significant step towards challenging anti-competitive practices and holding tech companies in the COMESA region accountable. The outcome of the investigation could mean that dominant tech companies operating across Africa must adopt open, competitive digital ecosystems instead of leveraging their market position to sideline rival AI providers.
