This is a classic example of a joke that writes itself.


Apple's original parts... some of which are probably (sort of joking here) manufactured in the same factories as the stuff from random Chinese companies.
Bigger question. Why would these Chinese companies
want Apple's OEM parts anyway? I assume you're talking about companies making fake Apple products. OEM is no advantage to them. They're making fakes and it's not like an average consumer can tell the difference between Gorilla Glass and a replacement panel. Same goes for any other part.
