I can only speak for things I've observed or talked about with people, so my perspective is necessarily limited.

What is the current consensus regarding Indians in China?

I suspect that for most it's not given much thought. Indian food is well-regarded as exotic, yet palatable. It kind of occupies the same space as Italian food in Canada (right down to being largely inauthentic). For a long time, Indian soap operas were a major hit on television. Nobody in my household watches television any longer (we've all switched to streaming to private devices) so I don't know if that's the same now. Several of my friends used to go to India once a year and loved it there. One of them wishes he'd stayed in India, in fact, because it seems he'll never get back given the state of the pandemic.

So largely I suspect the opinions, on average, range from "don't know, don't care" leaning toward approval.

What is the consensus regarding topics like privacy, anonymity, Tor, censorship et al, since I advocate privacy stuff (r/privatelife, c/privatelife and also mod c/privacy), and China does not have the kind of privacy/anonymity culture like in Western “freedom” countries? I have never gotten an opinion on it from China’s perspective, and it is just a very odd question.

This is one area where the Chinese are definitely different from westerners. Privacy and anonymity are not huge cultural touchstones. While at the same time they cheerfully use the very kinds of services I'm using to circumvent the Great Firewall because the "Golden Shield" (to give it its proper name) inconveniences them at their work and play.

If you were to go on about anonymity here you'd get people wondering what it is you're trying to hide, likely causing suspicion, not "HELL YEAH!" responses.
