Dude twitter doesn't get any more subsidy than any other private property generally benefiting from functional state. If you want communism that is fine, it is not immoral to want communism. But you could also just ask the state to; 1. Demand interop, just like it demands standardisation in other industries. 2. Run public servers that enforces the "unbiased" algorithm that you claim possible. These are reasonable demands, but they don't get you reach, any more than Bluesky or Mastodon architecture does, you can't force people to read your data.

I think you are defining "reach" differently than I would. Like being explocitly squelch in the algo regardless of follower count is different than merely having a low follower count. We can agree on that? Again it reads to me, that if we didn't already have a first amendment, you would call that communism too

that's like saying the first amendment requires newspapers to publish every letter to the editor. you are living in a fantasy world my friend. the first amendment only limits Congress from passing a law that would infringe on free speech

What? It does quite a bit more than that lol. See aforementioned case regarding pamphlets and the public square We are reaching levels of reductive I never thought we would

How about this, social media platforms must publish their content recommendation algorithms (including criteria for shadow-bans, containment of reach, banning, and so on.) As well as a log of their suspensions and bans and the specific reason for them. Would have bipartisan support. Wouldn't be onerous to satisfy (they wouldn't even necessarily have to host what they publish, it could be hosted on a regulatory agency's site.) And that's just thinking of low-overhead solution off the top of my head. Unfortunately, I think you are attached to the problem too much to accept that there is a solution.
