Possibly, but that might also just be a rationalization for protecting your interests which are generally aligned with those of your country. There are many variables, but I don't think that "China mistreats it's people" isn't high on the list for "We need to keep Huawei out and rely on US technology only". Technological and economic influence/power are much more important, Realpolitik wins every time.

And I repeat, I remain genuinely horrified that the same people who rail on incesantly (and justifiably!) about US abuses are willing to rationalize, explain away and ignore those of the PRC.

Are you absolutely sure it's me doing the "rationalization for protecting your interests which are generally aligned with those of your country"?

Yes
