We are not saying that google doesn't have the right to do with their OS what they want, although that has more limits than you say. However, yes, they have the unlimited right to make it the privacy-invading, closed-source in reality, complete mess that it is. They are not allowed to make it deliberately destroy competitors' systems, which it does. If you build a television that searches out my television and targets it with harmful interference if it isn't one you make, then you have violated the law. You have the right to build a television, but not to destroy mine. No matter how complex your system to destroy competition, no matter how many other useful things it does, no matter how much value people get from it, no matter how much effort they went to to create it, and no matter how much worse the competition is, you don't have the right to do that. It's wrong, and it's illegal.
