As a US citizen living in the US, even if the Chinese were to have every bit of my private data, they wouldn't really pose any threat to me as I'm not in their jurisdiction. The US, on the other hand, has a very real ability to use my data against me.
With very few exceptions (e.g. you are being explicitly targeted by a hostile nation-state for high-profile activities), surveillance by foreign governments will always pose less risk than surveillance by your own government.
However, I'll counter with the idea that while I as an individual am at minimal risk from direct legal action from China, the greater collection of data as a whole on say American's could be used maliciously. One example would be "Cambridge Analytica style" targeting of advertising, similar to the previous US election.
What I mean to say is that this data may pose a strategic advantage for China in ways other then targeting individuals. Yes the US can do this to me as well, but again I'm more confident in our system of checks/balances to at least minimize the damage.
Again, I do oppose all State surveillance, I just mean to voice my opinion the "lesser of the two evils"
For a limited definition of 'power projection'.
I am of the opinion that we are in the midst of a paradigm shift from overt physical power to weaponized and atomized informational power.
That is to say, the use of information technology and very fine-grained details about individuals to achieve ends that suit those projecting power.
I apologize, I didn't mean to come off as snarky. What I mean is that it's my own country. If I was from say Sweden, I'd likely trust the Swedish government more as a Swedish Citizen.
You wouldn't believe. Sweden is really a high-trust society. You can look up any person in the country online, etc, etc.
