Those people should be able to avoid the profiling, but any solution should be aimed at protecting those people, without impacting the 95% who don't care enough to give up convenience or pay for private services too much.
Almost everyone I know is on Facebook and Gmail, most seem to use Chrome, etc.
It seems to vary a lot with subculture. Programmers always seem to be more willing to sacrifice convenience, and people who watch porn seem to be more interested in privacy than most.
I suspect there's a pretty large segment that only cares in theory, at most, and only then just on principle because of the other people who have more interesting data.
Maybe not 95% but probably 90% of certain subsets at least.
