Ah the first four things are pretty amusing to native Chineses, but I’d say for locals they probably never thought it’s related to any sort of oppression or censorship (they think the cartoon was cute and btw Chineses love polices around don’t ask why...). Upper class Chineses are more aware of surveillance and they have some countermeasures but most people don’t really care and even support it. Yes there were attacks before so many places in Beijing has absurd security control.

There’s definitely a privacy issue there but it’s close to impossible to raise the awareness of Chineses unless something drastic happens.

Edit: Perhaps I have a low bar of human right issues but those you described doesn’t seem like red flag to me
