Just in case you haven’t heard about this man:
and if you truly reject that the big IT companies (which are US companies) - let it be FAANG or GAFAM I don’t know what you are doing here in this forum 
I think ajlok described it very good. It’s not about the US people or Chinese people. It’s about their governments and about global companies. Governments and companies work hand in hand to abuse and violate our rights. That’s where Purism comes in.
The post is about putting a label “Made in USA” on a product, while this is (at least for me) not seen as something which is pro-privacy - all the contrary. That’s why I also think there are two stories mixed. For me it would have been sufficient that they say that they control more part of the chain (where the country shouldn’t matter so much). So my personal speculation is that this is to promote purism more to the US market. Which is fine for me.
