> the fact that PRC Taiwan and USA all legally recognize one China policy
Notice how you use the term "legally." You know that in fact, most nations around the world treat Taiwan as a de-facto independent nation. The USA's formal word on this is as follows: "acknowledges that all Chinese on either side of the Taiwan Strait maintain there is but one China and that Taiwan is a part of China"
Notice how it does _not_ claim that the _USA_ thinks there is only one China. Only that it recognizes PRC and Taiwan do.
> Apple need to operate in the boundary of law
Apple need operate in the boundary of PRC law if they want to keep their Chinese factories, workers and profits, and that's what this critique is all about. Nobody else cares if they have "made in Taiwan" on their parts or products. In fact, I'd prefer if they did as it's more transparent!
