I can't see how anything less favorable to the devs would not be instantly rejected in court, especially in the EU ? Speaking of which, I don't see why the Unity using devs can't just keep using the old version of Unity, and therefore never have to accept the new license ? (Of course I assume that Unity would have made it extra-annoying, because these changes don't just come out like that, but the point here is to give themselves time to find an alternative to Unity.)
