WhatsApp Warns EU-Mandated Interoperability Opens Privacy Risks
-
WhatsApp is opening up its platform to comply with EU regulations, allowing interoperability with third-party messaging apps.
-
However, WhatsApp warns that allowing third-party access breaks its end-to-end encryption promises, as it can't control what happens to messages on those third-party endpoints.
-
Interoperability inherently degrades encryption and privacy protections compared to keeping chats within WhatsApp. Users face serious new risks.
-
Major competing messaging apps like iMessage and Signal are unlikely to participate in interoperability with WhatsApp.
-
Users can opt-out of interoperability if concerned about privacy risks. Experts recommend sticking to separate encrypted messaging apps.
