It chops pieces off reality when you do that.
Censorship is amazing. So popular (downvotes anyone?), so casually employed, yet so incredibly destructive.
If you've ever watched the banal things that people go through to get something past daytime censors, or, get a PG rating for films etc. it's similar.
This is not 'Xi's authoritarian' system so much as 'different cultural standards of the moment'.
Respect that in some parts of the world they don't talk or joke about STD's in that context.
I wouldn't want to be subject to it, but this is not the kind of censorship that's a problem.
Note that in the West, we 'self censor' tons of jokes or things that might be a bit off.
Finally - I'm 100% certain there are examples of this kind of censorship which are problematic, for example, the mention of 'Taiwan' etc..
I read a scifi where digital personality-recordings became popular for various office/industrial applications. Sorta like an AI, but human. They were used for censorship. The remedy for ideological contamination? Full reboot every morning.
I'm sure they all know about Taiwan as well.
So mostly it's just keeping programming in terms of what they define as 'civil' - and - with the added element of pulling 'political censorship'.
It's about large audiences and averages not about the knowledge of a specific thing.
Some people just have no sense of humour and a fanatical devotion to a cause, they are useful if not very wise. This is one of those situations where they are useful.
