Regarding #Brazil banning #X :
After the disaster of the Weimar Republic, the Federal Republic of #Germany came up with the concept of the "Wehrhafte Demokratie" - a "democracy that can defend itself". Fundamental to this concept is that people, groups, and organizations who want to overthrow the basic democratic order should _not_ get a "level playing field".
So while I can understand people worried about any kind of #censorship , I think by this standard this action is justifiable. Brazil went through an attempted coup, and X - and Elon #Musk - were instrumental in aiding the coupists.
And by now Elon Musk has established a clear pattern of "wanting to overthrow the democratic order" - _any_ democratic order. Thus, it is valid if Brazil wants to restrict his speech.
I see this as part of the "Paradox of Tolerance" - tolerating the intolerant will result in less tolerance. And tolerance, like freedom of speech, are social contracts. If you break the social contract - as Elon Musk has - then there should be consequences.
