FWIW I still hope Elon succeeds with Twitter. Why wish failure on anyone? But for me, not letting people post links to their other accounts was just too much.
I think it's a question of what success looks like.
So far Elon has spent an awful lot of time amplifying far-right voices, starting with that deleted homophobic conspiracy theory tweet about Nancy Pelosi's husband, and continuing with taking directions on who to suspend from some of the worst alt-right trolls.
He's also actively rejected taking steps against COVID misinformation, which is the sort of thing that can, in aggregate, kill people.
Should we wish him success in that?
