The European Commission has warned Meta Platforms that a fee it imposed on third-party AI assistants seeking access to WhatsApp violates EU competition rules. Brussels said Meta's revised policy appears to produce the same effect as excluding rival AI tools from the platform, and announced it intends to order the company to roll back the measure. The interim order, which regulators can impose when there is concern of imminent competitive harm, will remain in force until a full investigation into Meta's conduct is concluded.
