link, which, aside from the snarky tone, actually makes a useful point about social media -- which is that, both members and advertisers alike actually don't want totally unfettered speech as a value. They want safe spaces to play and to advertise, and what that means for Twitter is that "you have to ban racism, sexism, transphobia, and all kinds of other speech that is totally legal in the United States but reveals people to be total assholes. . . . the dull reality is that you still have to ban a bunch of legal speech if you want to make money."
Musk may be able to find value at the margins -- slightly more centrist mods, for instance -- but the sea change his backers and cheerleaders want to see will almost certainly not materialize; and if it does, it will almost certainly kill it outright.
