The fact that Musk previously said he wouldn’t ban the account, then changed his mind (apparently after a personal incident) just shows Musk changed his mind, is all.
It certainly demonstrates he didn’t think through his previous decision, suggesting it was a spontaneous comment and not a rigorous policy. Which is worrying, because publishers such as Twitter need to have a consistent and coherent moderation policy.
But it’s still relevant if we’re to decide which position we agree with, and whether Musk was “right” previously or now.
