I don't think removing all ability for moderation is a good idea, more of a balance is necessary.
Moderation is solved problem. There are email spam filters, network of trusted people, proof of work...
Anyone posting something outright illegal on a social platform is making themselves a target for law enforcement anyway — why subject the entire platform to censorship on their behalf?
In case of unmoderated social media, just because law enforcement goes after them doesn't mean the content doesn't need to be taken down sometimes. Think non-consensual nudes, calls to extremism, etc. These things are filtered out because at some point even Parler and Ruqqus and all will delete them. But completely unmoderated social media will not allow for that.
I also never said that free speech was less important than dealing with the Parler crowd. I'm just saying it's a harder problem than it's made out to be.
With well designed communication tools, you don't need moderators to decide what kind of content you see. You and your immediate network will be your own moderators by implicit action and inaction (and if everything is designed right, you can also take explicit action to e.g. drop that flat earth shit from your feed that shows up because your best friend keeps reading and upvoting it).
This is exactly how the real world works too. I choose who to chat and hang out with, I don't need to call cops to remove marketers and idiots from the world for me.
We’re talking text here btw, so CP/gore/revenge porn don’t count because those can’t be transmitted over text (links aside).
And if you want to do that as a centralized network, you'll be cancelled by one of services you have to rely on anyways.
I can understand the tendency if there's a business behind it, maybe they don't want the homepage to be filled with polarizing, divisive, or nsfw content etc.
But I do like the idea of letting users decide what they'd like to see other than on the homepage, where I would be Ok with some default filters. Maybe they can be disabled for the inclined.
