Goodwill. Just because you're the big gorilla and can act as such with impunity doesn't mean you ought to constantly remind people of that.

Their relationship to us has always been in very simple terms: These are the ways you're allowed to behave while doing business on our platform. Accept that, or do not publish here. If you publish here and break these rules, you will be removed without second chance.
Yet again, and again, and again, we get pleas from fellow developers who broke those rules but think Apple's just being mean. No, they're not. They outlined exactly how you should not Do the Thing, and you Did the Thing, and now you're off. This situation is fixed, and you knew the outcomes. You made your bed, sleep in it.
