I feel that some of the biggest noise made about censorship are those who have been guided by the subtle hand of social compliance. From figures of authority who share lols about lefties wanting rights for flowers, they are drawn into a world where they start willingly running with whatever they are being told, as long as it comes from those that they are compliant to. Eventually, they are shouting about how their very valid different opinion on why the holocaust was overstated is being censored, why can't they say their view, it is the corporations, deep state and Soros pushing these views down.
Personally, I got fed up of the endless circles that you have to dance around with the bad faith actors on Twitter, so I binned it off. For gaming, a past time that is plagued with a shitty audience, one of the best communities I have been part of is heavily moderated. Some would say that this is censorship, I just found that it was conductive to creating a positive community.
Eventually you have to draw the line in front of some things. There are massively obvious instances of content you have to control. A blanket statement of "allow everything" or "disallow everything" really isn't going to cut it. It's a really hard line to draw, though, and it is far from cut and paste.
They often are as a space can be created to facilitate purpose and action. Universities used to be places with open discussion, now they are places where anything that might offend anyone is closed for discussion. "How's the weather?"
Now I can't comment on what is going on at universities. Over here, I've generally picked up on dissent towards "trigger warnings", which have been translated as "we cannot talk about" where they really are "here is a thing that we are going to talk about" - i.e. a useful thing for PTSD experiencing individuals.
But, for the gaming community, the closely adhered to moderation cut out the toxicity and replaced it with actual proper discourse. Naturally, one size doesn't fit all. You can't slap down a rule for all, and that makes things hard work.
