EU spies on it's own citizens, as does Russia. They spy on foreign people as well. As does China.
But here is a shock for you all: So does US! Actually, biggest spying scandals are made by US government in the last 10 years.
So if spying is of any concern, then don't purchase a smartphone. Any smartphone.
I bet that china is spying or at least trying to spy on some of prominent US citizens, of course they are. But I highly doubt that they find some random folk interesting at all.
Industrial espionage, or spying on US government/military - of course.
But spying on regular Joe who posts on twitter, facebook and searches for p0rn - I don't think that they are that interested in you
