We certainly don't have much choice when it comes to choosing chips. It's an incredibly expensive process and only a select few superpowers can successfully maintain semiconductor industries.
Unfortunately, with some rare exception, they're not allowed to make x86-compatible chips, because the U.S. has worked long and hard to forbid the ISA, and everything used so far to implement it, from being standardised and thus kept under an unbelievable weight of patents.
Hopefully the build-up of more European fabs, and realisation that the EU has to make its own chips, will eventually remedy some of this.
They seem... certainly not more trustworthy than US companies.
Take whatever side you want, but at least keep to the truth.
