I mean, if you take it as a case for why moderation is hard, that's fair. But while Elon describes himself (identity politics) as a "free speech absolutist", his concrete proposals seem to include things like an edit button, long-form tweets and some monetization strategies.

I think the fairer critique of modern Twitter is that it prioritizes the needs of media personalities and PR firms over ordinary users, not that it isn't "free" enough. I am blandly optimistic about the prospects of things being shaken up at Twitter, and for who Elon is, it could easily be someone much worse.
