I dunno... I think people care about the privacy loss they can readily see. No one wants a big-ass window in their bathroom without privacy glass, right? But that's a loss of privacy that is hyper-obvious.

Google lulled the vast majority of us, myself included, into buying into their stuff, so that giving it up now is giving up massive convenience compared to what many look at as a much less significant privacy loss than someone being able to spy on them in the shower.
