The Chinese Communist Party places a high priority on social harmony because that’s what benefits them. Having freedom as long as no one notices you isn’t freedom.
In the US there is a faction that is extremely strong on "privacy rights". This seem motivated by the idea that you are free to do as you please so long as you can prevent others from knowing about it, rather than depending on having strong rights to do as you please whether others know or not.
Strong privacy is the "security by obscurity" solution to being free.
So you're arguing China has strong privacy rights? How do "privacy rights" matter if you don't have the freedom to have privacy?
