I don't think the retroactivity was ever legal, but small developers wouldn't be able to defend their rights in court, and the fact that Unity stooped that low revealed who they were. Nobody can ever trust them again, especially with the possibility of future retroactive changes being explicitly open. The good part of the news is that developers who are currently working on a game can still finish it without submitting to the news terms. That is incredibly important and will save many games. But it's not going to save Unity from itself.
