This occurred after the social network's chairman Elon Musk refused to appoint a legal representative in the country, which led Moraes to freeze Starlink's financial assets and impose fines for non-compliance.

After the attack, Moraes ordered several social media platforms, including X, to block specific accounts that had been involved in the planning, stating that the companies would be fined if they failed to comply.

[18][19][20] In response, Moraes said that he was opening an investigation into Musk, which the Associated Press described as focused on "the dissemination of defamatory fake news and ... obstruction, incitement and criminal organization.

[28] On 30 August 2024, Alexandre de Moraes ordered internet service providers to block access to X, instaured a daily fine of fifty thousand reals (US$9,104) for users who bypass the ban through virtual private networks (VPNs), and froze Starlink's finances in Brazil.

[32] In the order, Moraes described Musk as an "outlaw" who would "allow the massive spread of disinformation, hate speech and attacks on the democratic rule of law, violating the free choice of the electorate, by keeping voters away from real and accurate information.

[43] Reacting to the decision, Musk wrote on his X account: "Free speech is the bedrock of democracy and an unelected pseudo-judge in Brazil is destroying it for political purposes.

"[44] Shortly after its suspension, X created the "@AlexandreFiles" account, purportedly in order to shed "a light on the abuses of Brazilian law committed by Alexandre de Moraes".

[46] In an interview on 30 August, Brazilian president Luiz Inácio Lula da Silva emphasized that Elon Musk should respect the decisions of the Supreme Federal Court, criticizing him for allegedly offending local authorities.

"[47][49] According to journalist Andréia Sadi [pt], behind the scenes at the Supreme Federal Court, the judges assessed that the decision was severe but necessary, as Musk was believed to have intentionally escalated the situation.

Sadi reported that there was a consensus between judges that, despite this, Moraes would have committed excesses by blocking the Starlink accounts, which could potentially tarnish the image of the Brazilian judiciary.

Right-wing Nikolas Ferreira, a member of the Chamber of Deputies, stated: "Tirants [sic] want to turn Brazil into another commie dictatorship but we won't back down.

Right-wing congresswoman Bia Kicis stated that "the consequences of Alexandre de Moraes' attacks on Elon Musk, X and Starlink will be regrettable for Brazilians".

"[51] The decision to block Starlink's financial assets in the country was criticized by Arthur Lira, the President of the Chamber of Deputies, at an event for investors promoted by XP Inc.[53] In the United States, Wisconsin politician John Macco called for the relocation of the National Football League's game in São Paulo on 6 September (which featured the Green Bay Packers) to the United States, citing the blocking of X as one of his reasons.

Meanwhile, El País stated that Moraes' decision represented a stringent public sanction concerning the limits of free speech and efforts to combat disinformation.

American journalist Glenn Greenwald questioned the legal basis of Moraes' actions, suggesting that the judge was effectively creating new laws without the oversight of Brazil's Congress.
