It's all gone off (quite literally) because of a row over disinformation, at least disinformation according to a high court judge in Brazil, obviuously not Elon Musk who is a radical free speech advocate.
Moraes, the only high court judge involved in this, asked X to remove the profile of a senator of the republic and a 16-year-old girl from the air, but he didn't say why and in Brazil there is no law on disinformation. The legal process is to report it to the public prosecutor's office and only then go to trial, but what Minister Moraes does doesn't have that, he puts it in a process that started in 2019 that even served to annul the trial of the biggest corruption scandal in Brazil, this process never ends and serves to persecute.
Note: In Brazil, a senator has a law that allows him to say whatever he wants without being punished for it.
"Art. 53. Deputies and Senators are inviolable, civilly and criminally, for any of their opinions, words and votes.
The Brazilian State did give X a chance to stay open, but X failed to comply with the State's demands: namely they failed to pay a fine and to appoint a new legal representative as requested.
Elon Musk removed all Brazilian employees for fear that they would be arrested, and the Supreme Court Justice took advantage of a loophole in the law to ban X from Brazil once and for all.
He then tried a further subversion of the block more recently by updating its communicaation network so access to X was routed outside of Brazil, via Cloudfare, but this has since been remedied.
NB Cloudflare had to co-operate with this because you can't just blanket ban all traffic going through Cloudfare, that'd ban half the internet apparently!
It's not true, see what Matthew Prince, CEO of Cloudflare said about the case.
All this was happening when a scandal was being leaked on Twitter involving this Supreme Court judge, who was arranging with other federal agencies to get those involved convicted.
RE: Brazil Shut down X/ Twitter, like I care!
