Whereas there was no meaningful change to how WhatsApp handles users’ data, individuals instantly interpreted the app’s privateness notification final week to imply that it was infiltrating every kind of private data — like private chat logs and voice calls — and sharing that information with companies.

WhatsApp rapidly mentioned individuals had been mistaken and that it couldn’t see something inside encrypted chats and calls. But it surely was too late.

“The entire world now appears to know that Fb just isn’t constructing apps for them, Fb is constructing apps for his or her information,” mentioned Moxie Marlinspike, the founder and chief government of Sign. “It took this one small catalyst to push everybody over the sting of constructing a change.”
