Sounds like just-world fallacy. There's plenty of examples of people who take actions that do not lead to desirable outcomes. The idea that people choosing something in itself proves its value is nonsense.
I should have been clearer. I'm terrified of the power corporation's have amassed through surveillance, but no one I know outside of the tech community sees a problem. Most see Google and Facebook as "benevolent overlords"[0]. How can we convince people that danger lurks in the future given their love affair with the free, life-changing services of the "benevolent?"

I'd bet the majority of people have no clue exactly how much data they collect, how much other info they're able to derive from that, and what they do with it. If you described what they're actually doing as a hypothetical, I bet many of those people would assume it's already illegal, because much of it sure smells like something that ought to be illegal.
On the positive side, I can report that I know many people completely outside of tech who are extremely concerned about these problems. They tend to be older generation incidentally…
