Easy people, don't waste your emotional energy. Microsoft has been collecting Android licensing fee for years now. Apple has the objective to kill Androids. And you think Google don't use patent to sue? These companies are all evils.
I believe Google has only used patents defensively. At least that's what I've heard their official position is, and I haven't heard anyone call them out for violating it.
So far Google has not been used patents offensively. That is quite a big difference.
