I do, but there is no data or evidence supporting said non-resident corporation is under control of an adversary, so why should I believe anything the government claims? If you're going to talk about security, just stop, nearly every component in your phone is produced in China, and you still use that everyday.
At the very least they have an export ban on the "algorithms" which is why they won't sell, and chinese control, especially under Xi, is well documented, so I don't know what kind of smoking gun you'd expect. It'd be more unusual if there was a laissez faire position by the government.
Regardless, assembly of an iPhone with Taiwanese, Korean, and Japanese components in China is not the same as mass surveillance as a service.
