Meta Implements End-to-End Encryption Across Messenger and Facebook

Meta has announced that it will expand encryption on its Messenger platform, making it more similar to its sibling app, WhatsApp. The update means that personal calls and chats on Messenger will be encrypted by default, ensuring that nobody, including Meta, can access the content unless a user chooses to report a message. The company plans to encrypt all Messenger chats using various cryptographic principles, including those used by the popular Signal app. This move aligns with Meta's goal of providing more privacy-centric services across its platforms, following previous privacy-related updates on Instagram and Messenger. However, the encryption push has sparked a debate on the balance between privacy and law enforcement investigations, with concerns raised about the detection of online child abuse activities.
