Yes, although you're more likely to be extradited from most of the West to the US than to China. So if you're a dissident against the US you may be safer using Chinese technologies.

What does this even mean? Being a dissident is allowed in the US going by google's definition. What's not allowed is stealing a bunch of shit and then giving it away to foreign nations like Snowden did.

I would be interested in seeing an actual "risk analysis" for people from different countries. While I would like no country to have my data, if China/US were the only (and exclusive!) options, I guess the actual risk of negative consequences from "who has the data" is not equally distributed.

I guess, in general, within chinas sphere of influence you are better off having the us have your data and the other way around (e.g., ending up in a chinese prison is 'unlikely' while in europe the same way it's unlikely that ending on an american nofly list or in guantanamo is unlikely while in china). The countries inbetween or people traveling a lot would be more interesting.

Unfortunately, the most likely scenario is that everyone gets the data.

edit: I put "risk analysis" in quotes, because it doesn't feel like the right word for this hypothetical thing.
