The European Commission has ordered Meta to grant competitors' AI chatbots free access to WhatsApp, pending an antitrust investigation into the tech giant's decision to block third-party AI providers.

• Meta must reinstate access for third-party AI assistants to the WhatsApp for Business API within five working days.
• This intervention by the European Commission aims to prevent "serious and irreparable harm to competition" in the AI market by Meta's conduct.
• Meta has reacted angrily, calling the decision "regulatory overreach" and vowing to appeal, warning of potential fines up to 10% of its total turnover if it fails to comply.

• Despite concerns about potential risks and security flaws, this advanced AI is now being made more widely available, with an intention to expand access beyond initial cyberdefenders.
