The tech sector is witnessing a crucial moment in the regulation of artificial intelligence as the European Commission has intervened directly in the operations of Meta. In a decisive move to protect digital competition, the EU’s executive branch has ordered Meta to restore free access to WhatsApp for rival general-purpose AI assistants. This intervention utilizes rare interim measures designed to halt anti-competitive behavior before it causes permanent damage to an evolving market.
The dispute stems from a shift in Meta’s corporate strategy late last year. In October 2025, Meta modified the terms for its WhatsApp for Business Application Programming Interface (API), effectively banning third-party general-purpose AI assistants from utilizing the infrastructure. This restriction left Meta’s own proprietary service, Meta AI, as the sole AI assistant available to the platform’s vast user base. Although Meta later adjusted this policy in March 2026 by permitting rival AI assistants to return, it introduced a steep fee that regulators argue was practically equivalent to an outright ban.
The European Commission launched an antitrust investigation into the matter in December 2025, following up with formal objections over the subsequent months. The regulatory body determined that Meta holds a dominant position in the consumer communication applications market within the European Economic Area. By cutting off access to an infrastructure that was previously open to third parties, Meta’s actions have been flagged as a prima facie refusal to provide access, which violates EU competition rules.
What makes this development particularly significant is the implementation of interim measures under Regulation 1/2003. This marks only the second time the Commission has exercised these powers, with the previous instance occurring in 2009 against Broadcom. Regulators deploy interim measures only when there is an urgent risk of serious and irreparable harm to competition. The Commission highlighted that the market for general-purpose AI assistants is at a critical developmental stage, a period when smaller players and new entrants must be allowed to challenge large tech incumbents fairly.
Under the legally binding order, Meta is required to restore access to the WhatsApp for Business API for independent AI assistants under the exact free-of-charge conditions that existed prior to October 2025. The Silicon Valley giant has been given just five working days to comply with the directive, and it must maintain these terms until the broader antitrust investigation reaches a final conclusion.
The financial stakes for non-compliance are exceptionally high. If Meta fails to adhere to the interim order, the European Commission holds the power to levy substantial fines reaching up to ten percent of the company’s total turnover from the preceding business year. Additionally, daily periodic penalty payments of up to five percent of Meta’s average daily turnover can be imposed to compel swift compliance.
While Meta must adjust its platform immediately, the underlying substantive investigation into whether the company abused its dominant position under Article 102 of the Treaty on the Functioning of the European Union remains ongoing. There is no legal deadline for the conclusion of the full antitrust probe, meaning the temporary free-access mandate could govern the WhatsApp ecosystem for a considerable time as regulators thoroughly examine the case.
