European Union regulators plan to order Meta to reverse a move that limits AI chatbots from rival companies accessing WhatsApp. The European Commission, the bloc's top antitrust enforcer, says Meta's decision to charge third-party AI companies for access effectively blocks competition. The commission opened the investigation last year over concerns about WhatsApp's practices. Officials say Meta's March decision to charge for access is equivalent to a previous ban. Meta argues that providing the service for free would unfairly subsidize select companies. The company claims small businesses would end up covering costs for larger firms like OpenAI.
