I think the main factor here is that the Chinese government spying on me likely would have no impact on my life, while the US government spying on me has a direct impact. So as an average US citizen, I should be far more concerned about US spying than Chinese spying.

I absolutely agree though, I'd be far more afraid of using a Chinese device as a Chinese citizen than as an American citizen using an American device. China has far worse human rights abuses, it's just the ways they can impact most Americans are minimal in comparison.

I feel it's reasonable for an individual to be concerned about your own country's human rights abuses first and foremost as those are the ones you're personally most likely to contend with.
