I am not ignoring anything. The fact is that Brasil has laws to fight disinformation and libel, and those laws are being enforced.
Your personal opinion also glances over the fact that Brasil was recently subjected to a coup attempt to drive the country into a fascist dictatorship, heavily pushed by a massive disinformation campaign in social media services like Elon Musk's Twitter.
What you are trying to glance over is the fact that none of this issue is related to free speech. Elon Musk tried to avoid complying with a nation's laws with a ill-advised stunt of pulling Twitter's corporate presence from Brasil. As expected from any jurisdiction in the world, not cooperating with the judicial system bears consequences.
To drive the point home, I stress the fact that Elon Musk did far worse to support fascist and authoritarian dictatorships attacking free speech, such as his support for Erdogan's regime censoring opposition and non-supoortive posts during the last sham elections. For that, Elon Musk's reaction was claiming that either some messages were boosted or all of them were boosted, and he claimed it's better to have some (only supporting a dictator) than none. But for Brasil, the need to appoint a mere legal representative to process requests was now deemed too much? And enough to pull a dying company from a +200M market? It doesn't pass the smell test.
