Actually Google currently is facing some serious anti-trust cases as well.
Edit: I was against the antitrust case at the time even though I did not like nor used MS /products/ and did not approve of their practices. I believed they got that power because they managed to get enough people drink the coolaid and that's a part of what a business does; kudos to them basically. Still don't like most software they make, but as a company it seems a lot better now. Why restrict that? I have another opinion (I would be for the antitrust case now) now as I grow older.
Google is really the same as any other big company. They will do what they can get away with to further their goals.
