I wouldn’t even look at it from an anticompetitive angle or anything like that. This is a matter of what’s best for apple and its users. They should absolutely do what’s needed to ensure that their terms are obeyed. But permanently banning google is not “what’s needed.” What’s needed is merely to demonstrate that the behavior will not be tolerated going forward. I imagine discussions between corporate lawyers and perhaps a reasonably sized bond would be sufficient to demonstrate google’s sincerity in not repeating the error.
