Note that wanting to see Twitter fail is not a violation of the TOS in its current form (although that may change next week). Having such a ban however doesn't jive with "free speech" though, so if that is introduced it would contradict with the idea.
Spreading misinformation may be, but people in this discussion so far have not posted evidence of that account doing so. However Elon already said he was doing general amnesty next week, very clearly including those that were known to spread misinformation. A very prominent account that was proven to spread misinformation had been restored recently, even ahead of such general amnesty, so if the subject account is not restored by then, I think it shows pretty clearly the policy is not being applied fairly.
Note that saying a particular account should not be banned is not the same as saying you support the views of that account. There is a famous phrase: "I disapprove of what you say, but I will defend to the death your right to say it."
I guess we'll see what happens next week.
