Should you trust Facebook? If you’re on it, you already do. Its faceless tentacles are fully embedded in your movements, prejudices and purchasing patterns. It knows more about your network of family and friends than any human does. You’ve given it enough information to clone you, voluntarily and without reading its terms of use.

That aspect of the evolution of privacy is done, along with the hope of ever again doing something embarrassing at the pub and it not being recorded on someone’s phone.
