Nothing's stopping nation-states from forking Linux-based systems and open source tools to circumvent Microsoft, Apple, Netgear, etc. There isn't enough political buy-in to wean countries off of Windows, Mac, Android, Intel, AMD etc.
German schools for a while used OpenOffice as Office 365 had too many privacy issues. But these are small-scale changes that are temporary, and don't go beyond the muncipality level [0].

The Chinese government could absolutely ban Chinese companies from selling to companies closely affiliated with the US Government if they wanted to and I imagine there are some Chinese companies/products that are subject to export restrictions.
Various governments around the world are enforcing different import/export/data rules to protect their citizens.
These things are all 'fine' or at least understandable and well within the expected behaviour of sovereign nations.
I would be happy to be proved wrong but how does being funded or managed or owned by PRC influence anything unless there are actual backdoors?
Just because huawei is funded by PRC does that make them guilty?
This Hn poster wrote this. So CIA is selling backdoored equipment which is fine for you?
another question.
What about someone in EU or africa or india. who should in your opinion spy on them? usa or china?
That being said, it's interesting that a lot of the China vs US heat started ramping up right when China rounded up a bunch of CIA assets in the country. It's arguable from a game theory perspective that everyone's better off with a bunch of spying so everyone knows what's really going on in a country. Transparency is usually considered good in other areas. I can't see why that wouldn't apply here.
It's also worth pointing out that by and large, it's very likely the important programs aren't spying on day to day citizens, especially as the war on terror has faded. They're just not that important, and it's riskier. It's economic, military, and political espionage.
Maybe just add a third neutral participant to have three spying forces for no breaks.
