It's not even that, if I was Apple I wouldn't want to have them as a customer simply to deny them standing for their constant lawsuits. If the two companies have absolutely no business relationship at all, ties completely severed then it's a lot harder to demonstrate harm. All you could really sue about is that they won't do business with you.

I'm actually surprised it's not SOP to stop doing business with people who sue you after the lawsuit ends. I mean you took the nuclear option.
