Replace "moderator" with "any peer".
Replace "block" with "vote". (And that vote could be as simple as "up down" or maybe something more sophisticated)
Now everybody you meet (every "peer") has a "rating". Based on the cumulative voting of yourself and your peers.
A peer that you upvote, his votes are weighted-up in that cumulative rating calculation.
A peer that you downvote, his votes are weighted down.
So we have peers, votes and a cumulative rating calculation.
And then we filter out view by rating.
Voila! Personalized decentralized moderation.
Communities function when there is a standard to which the community members adhere and when bad behavior is uniformly moderated away. Making each individual have their own moderation bubble is a recipe for incoherence, even with the improvements you suggest. Its also a lot of work.
FWIW I think it's a sign of intellectual dishonesty to complain vaguely about censorship of "widely held beliefs" without stating what those beliefs are. All social networks have "ground rules", they're just not always the same. For any social network that somehow can be pinned to someone's physical identity, those rules will at least include the laws of that person's jurisdiction.
"Free speech" is widely mocked as a supposed principle because it's a rallying call, not a specific thing. Even people who'll proudly tell you "I may not agree with what you say but I'll defend your right to say it" will have limits if you keep pushing them on it. "Free speech" just means "I want to be able to say things I'm not allowed to say" and the first response should always be "what and for what purpose".
To many of us the mockery of people who think that way is a badge of honor.
1) Reddit banned /r/NoNewNormal and "Covid misinformation" after activist moderators started shutting off subreddits. I personally got a Covid vaccine and complied with mask regulations, but I was interested in hearing coherent arguments related to lockdown / mask / vaccine skepticism. Obviously these skeptic views were very widely held beliefs, and some of them like the "lab leak theory" went from "misinformation" to "possibly true"
2) Reddit banned /r/GenderCritical which was a subreddit representing feminists who expressed skepticism over modern transgender ideology in the spirit of JK Rowling. Again, JK Rowling has millions of followers so this qualifies as a widely held belief. While I want to be inclusive and supportive of transgender people, I'm interested in hearing skeptical arguments related to things like whether it's really a good idea to give puberty blocker to teenagers .
I believe both of these bans happened not for good reasons but because of ideological crusades from Reddit power-moderators who skew heavily on certain political and ideological topics.
I'm not trying to start a flamewar or debate on either of these topics, I'm not endorsing either of those subreddits, I'm addressing your critique that specific examples were not provided of "widely held beliefs" that have been unfairly censored.
Through what mechanism do you believe website owners should be forced to allow users to operate by their own terms? Should anyone who hosts a comment section on a personal website be forced to keep all posted comments in perpetuity?
I would hazard a guess that don't think those beliefs need to be stated because most people know that widely held beliefs are censored, and because it would make the discussion about something else. The Twitterfiles are available, as are all the discussions about censorship including by those running the social networks. They don't deny censorship, they attempt to justify it.

Free speech is not a rallying call, and it most definitely is a principle, just as "democracy" is not a rallying call.
> Even people who'll proudly tell you "I may not agree with what you say but I'll defend your right to say it" will have limits if you keep pushing them on it.
And like democracy, different people will define it and (if they get the chance) implement it differently. However, they're all talking about democracy (maybe with the exception of North Korea's government).
> "Free speech" just means "I want to be able to say things I'm not allowed to say"
It most definitely does not mean that which means your following questions are moot. I would suggest that you find out what those supporting freedom of speech actually think.
To be a little clearer: you have your own private filters and a separate, distributed block list shared amongst your friends, which is for bad content. You use the big red button when you encounter spam or harmful content, and this bad content/user/node/etc is added to the shared block list.
You initially trust all of your friends to use this block list properly, but if you find one of your friends is misusing it you can revoke trust from them and ignore their contributions.
