Elon Musk's X attacks Moraes and praises Trump for implementing the Magnisky Act

An official X account praised the Donald Trump administration for imposing sanctions against Supreme Court Justice Alexandre de Moraes under the Magnitsky Act.

Billionaire Elon Musk 's platform said in a statement released Friday, March 8, that Moraes led a "campaign of censorship and violation of due process." One example of alleged irregularities is the suspension of X's operations in 2024 due to repeated failure to comply with Brazilian court orders.

The publication also claims that the Supreme Court's decision to expand the liability of big tech companies for criminal user content " removes a fundamental safeguard for freedom of expression online and reinforces a broader pattern of concern."

"OX commends the Trump administration's decisive response to the Brazilian Supreme Court's overreach, sanctioning Moraes under the Global Magnitsky Act and revoking his visa," the platform adds. "These actions set a precedent for broader deterrence."

What changes with the regulation approved by the STF

In short, until the National Congress enacts a new law on the subject, platforms may be held civilly liable for damages arising from third-party publications in cases of crimes or unlawful acts if, after receiving a request for removal — the so-called extrajudicial notification —, fail to remove the content.

Providers are also subject to civil liability if they fail to immediately remove posts that constitute serious crimes. This list includes content related to attempted coups, state abolition, terrorism, incitement to self-harm or suicide, racism, homophobia, and crimes against women and children.

Furthermore, providers will be held liable if they fail to take down illegal content displayed through ads and paid promotions. In short, they cannot profit from illegal content.

In the case of crimes against honor—slander, slander, and defamation— big tech companies will only have to pay damages if they fail to comply with a court order to remove the content. They can, however, delete the posts with an extrajudicial notice. This is particularly relevant as the 2026 elections approach.
