The situation is way more complex than a simple trade war; no matter who started it.
Part of the problem is that if Apple is relying too much on factories in China, then they are completely in the hands of the CCP; and the CCP have these past years implemented a lot of new laws that per definition are global, so if Apple even try to investigate the situation in East Turkistan, or in any way just comment on CCP actions/politics, then… well… it wouldn't be good for Apple business.
The proverbial powder keg already has a lit fused; the question is just whether or not Apple has enough time to exit enough of the manufacturing out of CCP-land before things blow up. Because people in the west will force Apple to uphold the standards that Apple says that they stand for, and that will sooner or later make them clash with the CCP.
