I know your comment isn't about Elon specifically and I have my own reservations about some of what he does, but it's important to point out (and maybe this depends on what you call "misinformation", it shapes all future discussion) that Twitter absolutely was censoring for partisan reasons (before he bought it; I know some have complained Musk does indeed ban his critics) including silencing covid dissent, real doctors and researchers getting kicked off. Him acquiring it was absolutely necessary to break the deadlock
Edit: We do not want our platforms to be owned by someone like Susan Wojcicki who inflated her own importance and who thought mass censorship is ok (Google has really abrogated their responsibility here)
