Sure but in this case the judge is not censoring merely incorrect information. It's written in the article that I assume you haven't read
The judge ordered to remove the account of a militant group that attempted a coup after the party they support lost the election
This is exactly the kind of thing that should be censored. Anti democracy groups
Your right to free speech ends when it turns into terrorism, racism or a call for a coup.
There are some things that should be banned, such as the twitter accounts that promoted the attempt at a coup in Brazil in Jan 8 2023.
These are the accounts that the judge asked to be banned. After Twitter didn't comply they started sending fines and eventually outright banning it.
Free speech doesn't mean you can say literally anything. It means the government cannot punish you for your political views. But they can, and must punish racism and anti-democracy speech.
Also, it's a misconception that a decentralized service cannot be banned. In fact it's not hard at all
