This smells like anti-Chinese FUD IYAM. There are plenty of differing qualities of parts, but they're not all official while some are the same. If R2R were a thing in the US and parts were commonly-available, there wouldn't be a need for white-, gray-, and black- marketplaces. Sure, there could be lower-quality ones when someone wants to do it cheaper, like there are right now.
