There is enormous difference between 'China' and the 'US' and frankly quite a bit between 'US' and 'Germany' and 'UK'.

Being able to hack into systems to hunt down individuals of interest to the state, is something totally different than everyone, everywhere, at all times surveyed, by everyone, even their neighbours, and then putting people in 'internment camps' because of their ethnicity.

This is all tricky stuff, it all needs context.
