Surely there's still subcomponents made in China, even if device manufacture happens in Taiwan.
Granted, it doesn't really matter from a security standpoint unless those subcomponents are ICs of some sort. Then again, there's probably some really clever ways to backdoor stuff even using "dumb" components.
It'd be nice if consumers had options for end-to-end supply chain assurances though.
Yeah I’m 99,9% sure that a non-negligible part of the subcomponents are made in China. I would be extremely surprised if it was possible to find a modern personal computer with zero parts made in China. (Might be possible for embedded devices?)
I don’t know for sure, but if I read that comment correctly, those six companies are turnkey suppliers for the large computer brands.
