It sounds like a big part of the problem is that we don't have a truly "public" internet, if the backbone of the internet is a bunch of private entities.
We need a truly decentralized internet that doesn't suck like tor currently does.
This argument is always about people complaining that they don't get to participate on the big platforms. But if there was so much demand for people shouting about racist loser shit online there would be a big platform for it. It's their responsibility to build it, not Twitter's
This is exactly what I was talking about here[0]. You don't want a place to post freely to exist because you already have a preconceived idea of what people will say, and you are against that. This kind of attitude is hidden behind so many of the "but you can already do X, kinda" responses I've seen before in these discussions.
Why not just lead by saying you don't think a government maintained platform for free speech should exist because you don't want to hear what people who want it would have to say?
The internet isnt just SV companies. There's nothing stopping you from creating your own platform that espouses your ideals.
