Meta Implements End-to-End Encryption for Facebook and Messenger, Defying FBI Opposition

Meta, the parent company of Facebook, has begun rolling out default end-to-end encryption (E2EE) for chats and calls on Messenger and Facebook, despite opposition from law enforcement agencies such as the FBI. The implementation will take months to reach all 1 billion users. Meta plans to use the Signal Protocol and its own Labyrinth Protocol for encryption. The company assures users that with E2EE enabled, it will not be able to read their messages, but users can still report messages to the company. The Electronic Frontier Foundation praised the move, but noted that it currently only applies to one-to-one chats and voice calls.
