This is not a matter of opinion, rather than centralized control of information.

Musk can shadow ban you, for example, nobody granted him that power except he was able to by it.

This type of social media are a power structure that is despotic in nature, and it is deeply problematic for democracies.

It is not like a nation state banning a religious minority or an anarchist site. That would be censoring of opinions.

In the case of Xitter, it is Musk and a team of political advertising engineers doing the censorship. So they are worse than Nazi apologists for example. The latter we only anticipate they will impose censorhip (let alone murder) once they are in power.

Xitter has that power already at orders of magnitude above what traditional media outlets have. He controls the flow of information. (And he made it a fucking nazi bar right enough).

But I will grant you that we should not expect nation states to ban Xitter. We should aim for its destruction.
