I don't really know what it is that Musk does on his platform or why he does it. The Twitter-Brazil incident however is about free speech. Brazilian constitution says that any and all censorship of political speech is prohibited. These were political accounts. This judge, a government official, ordered their banishment from the platform. Political censorship.

I’m not familiar with the specifics but a cursory examination indicates that the accounts were publishing libel.

Libel is not now, has never been, and will never be protected speech.

It also seems that Twitter failed on at least one occasion to appoint legal representation and I don’t know if that means counsel or a business point of contact so if this was whatever Brazil’s version of a default judgement is, that makes it even dumber.

Regardless, if someone (in this case Musk) throws their lot in with people who unambiguously attempted a coup d’etat in the name of free speech, they should be examined more critically than usual.

My examination indicated it was all due to "fake news" as determined by these judges. This is the first time I'm encountering the libel/defamation argument. I suppose it's impossible to know since I didn't witness it in real time and everything is secret.

I don't believe what happened was a coup attempt. They occupied Brasília buildings, that's the standard brazillian protest, happened many times before. They wanted the military to seize power and rule over them, and the military refused. They wanted the military to rule over them. That's a valid political position. A coup attempt is the military actually trying something. An actual coup is the military succeeding at it.
