There has never been such a powerful surveillance tool in the history of the world. 500 hundred million people -voluntarily- submitting every detail of their lives to the FBi machine.
That is why a feckless fellow like zuckerberg can do what he is doing.
Those billions? Pure sentiment, and, the poor fellow doesn't seem to know that he's as disposable as a few sheets of charmin.
On FBi ? you might as well cc the FBI all your communications and save the effort of logging in.
