I'm unconvinced that the US population cares enough about its data to get rid of Facebook anytime soon. The media goes berserk with every new breach, but even the Equifax debacle barely registered in the minds of most Americans. I don't see Cambridge Analytica as a tipping point, because most people are oblivious to the fact that people are deleting their accounts in the first place. Their infinite newsfeeds will be just as full of crap as ever.
