Google almost certainly spent a few of their billions on a team of attorneys to draw up a contract that lets them do anything they want, as long as it doesn't break the law, but also some things that do break the law because who's going to check, and insulate themselves from any developer action. Meanwhile, they also have the resources to make sure a challenge in court will last long enough for the other party to run out of money, and if someone smallish challenges them on this contract, I fully expect to see that tactic used.
