They tried a coup (with the military and the brazilian rural oligarchs), so it’s not “censorship”, it’s enforcing that Brazil is a democratic (even if very flawed) country. The constitution give this right to the supreme court and him (he was the supreme judge for the last election, so dealing with the aftermath of the election is his obligation), so it’s a lot more nuanced than you might say.
Edit: If Musk doesn’t respect our laws, let him get out of here haha.
Moraes have a case in his hand (the tried coup last year), because he was the supreeme judge for the elections. He judged that these people tried to help the coup and demanded that their accounts are suspended (entirely cool with the constitution), as musk doesn’t want that, they’re gone from Brazil and might be blocked countrywide.
