Fair, but at least in the US, if there was (somehow) a huge popular rise in the public's perception of privacy, and there were marches every day for weeks, we could maybe get a law passed. I'm not holding my breath for this to happen and the political situation in the US of the past 6 years has not been encouraging, but at least the legal framework for change actually exists. Voting barely works but at least it's not illegal.

Do you really believe there is no such mechanism in China?

Which mechanism allows this in China?

Voting. The main difference is that the division line between parties and government is placed differently than in democracies. There are advantages and disadvantages of course, but the main point is: it’s silly to believe there’s no social feedback mechanisms in a country changing as fast as China does.

It's a one party state? Operating under omnipresent censorship?

There certainly are street protests, usually in response to local incidents, but the whole transmission mechanism is extremely limited to the bare minimum. And certainly not capable of discussing privacy in any Western sense.

Because the division line is shifted, the term "party" means something entirely different. So, yes, in one party state there are still groups within it, with different beliefs about things, and they work toward consensus using voting. Street protests are just one of the forms of democracy (and they are often organised by party).

As for privacy in the western sense - does this include USA, with no personal data protection at all?

No dude Chinese people can't protest they are all stupid drones... /s

Replace "stupid drones" with "thrown in jail, families abused, disappeared" and you have an accurate, non-sarcastic assessment.

Look to our friends in Hong Kong.
