But you trust "US" phones (made in China or elsewhere), where the data you store on them could actually be used against you?
From the perspective of the global citizen, arguably the USA would present more unilateral risk. The USA wouldn’t hesitate to act in their own interests in a way that screws others over. Then again, China has even less scruples, so it’s a lose/lose situation here.
Plus I have nonzero but small legal rights and remedies to mitigate my own country's surveillance of me.
