WhatsApp is working on a new feature that lets users translate messages directly within the app. This feature uses Google's live translation technology on the device itself to ensure privacy. Users will likely need to download language packs, and translation support might be limited at launch but will expand in future updates.https://www.notebookcheck.net/WhatsApp-is-reportedly-bringing-Google-Translate-to-chats.861346.0.html
Anything to steal your "end to end" encrypted data back to google
Most ordinary people are so stupid and technically uneducated that they do not understand banal and completely obvious things.
In a commercial business project that is free for users, there cannot be unbreakable encryption at the user level with data inaccessible to the owners of the business project, since you (your data) are what is being sold.
Everything that is transferred to the servers of such projects is, by definition, public information that is sold to third parties and used for the benefit of the project owners, and only idiots believe otherwise.
Safe p2p encryption is a pure lie by the owners this projects, as and in Telegram (his owner, for example, eventually admitted that he was lying)
