How do you attack the actual thing? Some are trying with copyright lawsuits and potential gov't policy proposals I guess but it's much easier to attack a single company and get an army of outraged allies over something easily digestible (an advertisement).
I agree that there's two things: doing something about it, which is hard, and complaining about it, which is easy. What I'm saying is, if you're going to complain about something, might as well complain about the real problem rather than a harmless symbolic representation of the problem.
