> The majority of people don't really care how corporations behave.

This is not true, people care, but not enough to make them stay away from Google. Violating privacy is not that high on most people's mind. If we knew, for example, that Google search engine uses child slave labour, a lot of people would stay away from it. But if it's just remembers what you searched for, most people kinda care, but not enough to inconvenience themselves by using something else. It's not binary, it's a spectrum. And new developments move people's opinions along this spectrum.
