Barely anyone cares about online privacy. MS found that out with the failed Scroogled campaign which they scrapped after it tanked. People value free stuff more than privacy.
There are some interesting court cases going on though, with the analogs of your scenario but with student data.

it tanked because it was a terrible campaign not because people don't care about online privacy. The fact that it was MS all of companies running it made it even more terrible.
I suspect you are confusing not caring about privacy with a feeling of powerlessness mixed with a general ignorance of any alternatives (which might not exist in some situations). The meme that people want to give up privacy in some kind of barter for services is just projection and wishful thinking in most cases.
