Messenger chats can now feed Meta AI, and there is no real opt-out

Facebook Messenger chats and photos may now be shared with Meta AI, a change that has alarmed privacy-conscious users given Meta's years of promoting end-to-end encryption across Messenger and WhatsApp. Users cannot opt out of having their content used to train Meta AI, and posting declarations on a profile refusing permission has no legal effect.

The limited mitigation steps available all come with caveats. Keeping the @MetaAI assistant out of group and personal chats reduces exposure, but anyone in a chat can still share its messages and photos with Meta AI. Deleting or editing sensitive messages is the second option, though there is no guarantee deleted content is erased from Meta's servers. The only complete solution is to stop using Meta's apps for messaging altogether, and WhatsApp is Meta-owned as well.

Alternatives cited by privacy watchers include Signal, Telegram, Voxer, and Discord. Signal in particular is gaining ground: multiple U.S. federal workers, speaking anonymously to reporters, said they have moved sensitive conversations from text messages and Messenger to the encrypted app amid growing distrust of large platforms.

For most users the realistic outcome is continued Messenger use with greater vigilance about what gets said and shared, since the platform remains deeply embedded in personal and business communication.
