Personally, I don't. But not everyone is able to (for lack of awareness to alternatives, technical skills, software constraints, work requirements, vendor lock-in, ...). Are those people unworthy of being protected from an evil company's wrongdoing just because they're using the "wrong" OS? You're basically arguing that corporations can do whatever they please "on their own turf". That's not true as far as user rights, consumer protection and anti-trust laws are concerned. And it shouldn't be.
