I'll say something unpopular: Section 230 should be repealed.
I agree with this, but I disagree with your reasoning.
It used to be that to be not held accountable for the things your users said you had to be a "common carrier", solely the transporter and nothing else. You didn't meddle in the content, lest you are no longer a "common carrier".* The "communications decency act" (well before Cameron came up with his "good and clean internet" infamy) turned that on its head. So now, to not be held accountable, companies must play content police on their users.
This is stupid on many levels. It is also a subervsion of the US constitution's first amendment: Instead of making a law to curb freedom of speech, which the government shall not, it made a law to make others curb freedom of speech. That is unconsciable.
Also note the sophistry: "Decency" is not something for politicians to impose on other people's Communication. Nevermind that the US constitution's first amendment already ougth to have informed said politicians that they're being more than usually stupid and petty. There is a reason for that amendment and if you don't understand the reason, you have no business being a federal politician.
So I say, if you really want to avoid the entire moderation (censorship) debate, you simply do not moderate (censor). Certainly not in the sweeping world-wide manner that, say, twitter and facebook de facto do. They should have implemented a killfile for individual readers their personal use and nothing more.
They aren't there to protect people's sensibilities, they're there to convey messages regardless of content. Moderation, if you wish it, ought to be done USENET-style, on topical groups and by and with the consent of the users of said groups. Anything else is external parties imposing their editorial views and therefore censorship. This is a point lost on quite a few people and even the companies doing the censoring themselves. But that failure is the root of the problem.
As to the US Capitol mob, the important point is that these people feel wronged, and that at least the "election was stolen" part needs addressing. Instead I see politicians mobbing up on the vanquished and I see calls for more censorship, because addressing grievances from your political opponents is just so not done.
* Notice how ISPs injecting advertising in user http streams, and ISPs fucking up DNS, for which the tech-wankers at mozilla came up with "DoH"-non-solution, would fall afoul of the "common carrier" notion. That is, if you take "DO NOT MEDDLE WITH CONTENT" seriously.
