Well... on shoring the hardware is kinda Cooks specialty. If anyone can do it, he can.

From the service revenue perspective, you can simply play hardball. Threaten to pull out of markets and ensure it's locked in litigation, forever.

Offshoring is Cook's specialty. If he was any good at onshoring then Apple wouldn't be in this position to begin with.

It's too late to play hardball, anyways; Europe has already started enforcing their legislation and America's own DOJ has already prosecuted an antitrust case against Apple. There's no more room to give Apple impunity because everyone admit that they've abused their benefit of the doubt.
