I think this is the main issue: that we walled up our discussion plazas to make them 'profitable products'.
I know I am a bit of an idealist here, but I miss the old-timey usenet, basically an agora where you could filter yourself (with the appropriately-called killfile), and which was not controlled by one institution alone). I had some hope with federated systems - but these are often built with censorship mechanisms written right into it, and again give operators too much influence on what their users may or may not see.
I remember the time when it was en vouge for subreddits to ban people for participating in subreddits they personally disagree with (automated, regardless of how that participation took place).
You cannot have a free exchange of ideas with a centralised thought police. You can only have truly free communication if you yourself decide what you read, and what you block out.
For bigger platforms which operate as a public forum I think the case is stronger for weak moderation, but even in those situations a bad faith actor (say perhaps a state or corporate actor with a lot of money to blow on bots) can completely undermine the purpose of those forums. I really can't imagine how a transparent moderation policy in such a situation isn't at least practically useful. In the end you cannot have a free exchange of ideas if some parties are intentionally manipulating, trolling, or flooding the zone of exchange.
Congress isn't just a free for all of people yelling at eachother. There are rules, not to moderate free speech, but to just make hundreds of people cooperating a possibility.
