It is perfectly fine to be upset about certain lawful behaviors because lawful does not mean good. This does also not exclusively apply to companies, people can be law abiding assholes. And it works in the other direction, too, sometimes unlawful behavior is good behavior.
But GP comment is not about how you feel about it. It is about where you direct that anger. If you dislike what a powerful entity does, well, we the people are supposed to have a recourse in our representatives. Why precisely is it that we feel like we do not?
