What Brussels ordered on 9 June
On 9 June 2026 the European Commission imposed interim measures on Meta in its ongoing antitrust investigation. The order is concrete: restore free access to the WhatsApp Business API for third-party general-purpose AI assistants, on the same terms that applied before 15 October 2025, within five working days, and keep that access open until the investigation ends. Executive Vice-President Teresa Ribera put it plainly: the Commission requires Meta to restore access for competing AI assistants while it investigates whether the restrictions infringe EU competition rules.
Interim measures are an emergency brake, used only when waiting for a final decision would cause serious and irreparable damage to competition. The Commission's reasoning is that the growing market for general-purpose AI assistants is exactly the kind of young market that can be foreclosed for good while a case grinds through the normal procedure. It chose not to wait.
How a messaging app became an AI chokepoint
The timeline tells the story. On 15 October 2025 Meta changed its WhatsApp Business API policy to shut out third-party general-purpose AI assistants, leaving Meta AI as the only assistant of its kind on the platform. In December 2025 the Commission opened an antitrust investigation, and in February 2026 it sent Meta a statement of objections setting out possible interim measures.
On 4 March 2026 Meta revised the policy and let rival assistants back in, but attached a fee that the Commission says appears equivalent to the ban it replaced. A supplementary statement of objections followed in April. The preliminary view behind all of this: Meta holds a dominant position in consumer communication apps in the EEA, and it used that position to keep AI rivals away from WhatsApp users.
The signal beneath the case
Two things stand out. The first is speed. Interim measures are among the rarest tools in Brussels, and deploying one for AI distribution says the Commission believes the fight for the assistant market is being decided now, in channels, not in benchmark scores. The second is that Brussels is not alone: Italy's competition authority has imposed interim measures in its own abuse-of-dominance case concerning Meta AI.
The underlying theory of harm is simple. Whoever owns the customer channel can decide which AI reaches the customer. Meta rejects that framing, says the order forces it to give large companies free access to a business product it built and paid for, calls the decision regulatory overreach, and has announced it will appeal.
What this means for your channel strategy
If your company runs customer service or a commerce assistant through the WhatsApp Business API, the decision requires nothing from you. It does reprice your dependency. The terms of a channel you rely on changed once, changed again five months later, and were then changed back by a regulator. Treat channel terms like supplier risk: know your exposure and know your alternates.
The practical moves are unglamorous. Inventory which customer channels you control outright, such as your site, your app and your consented email list, and which you rent. Keep a second channel warm enough to carry weight if terms shift. And when you contract for an AI assistant, ask the vendor in writing what happens to service continuity if platform access terms change. The appeal will run for months. Your channel map should not wait for it.
