The term Faustian Bargain comes to mind in regard to paying for commercial services with our privacy. Most people just straight up don't know what advertising is really about. Also, at least in America, we aren't educated about what's happened historically after super powerful institutions invert the privacy/transparency dynamic. Just because the human species hasn't, in the last 15 years, evolved to learn to weigh long term, abstract consequences on an appropriate magnitude with immediate gain does not justify those exploiting this quirk in human decision making.

Also, a camera on every street corner and spy agencies spying on you isn't what "voluntary" means.
