This is where you are inserting “arbitrarily” as both a statement of fact and moral wrongness.
Every single court in every single country has the ability to issue court orders on businesses that operate in that country. It is true in the US, China, the UK, North Korea, France, Australia, Myanmar, Spain, etc.
Name a country! That country has judges that can do things that you do not like. Even things regarding your personal definition of acceptable limitations on freedoms, speech included. And it can seem arbitrary to you.
Your issue is not with Brazil’s court, your issue is with courts in general. Except for…
> I assure you I don't really care for Musk or most of the things he does and (especially) says. That's entirely besides the point.
This is a thread about Twitter being blocked. Is there an any other action taken by the Brazilian supreme court that you have an issue with? If not, this is not a concern about the Brazilian constitution, this is a petulant billionaire screaming “dictator!” loud enough from his soapbox that even people that aren’t in his regular retinue of credulous followers fall for it.
> So a government censoring it's political opponents is fine as long as they are using a platform owned by a rich "libertarian" jerk?
If the judge is following the law, and his only actual sin is pissing off some crybaby libertarian for having to comply with the law, then the judge has committed no sin at all.
Anyway all of that aside, all of this actually stems from Elon Musk refusing to comply with an investigation and court orders around an actual attempted coup in that country. Musk’s credulous supporters will either say “that’s not true because Elon posted that it’s about something else” or “actually the coup should have happened because Musk said the current government is bad and we should support undemocratic government overthrows because Elon says they are good”
His side of this is literally nonsense. It is defended by unserious people.
