Major US tech companies, including Microsoft, Google, Apple, Amazon, and Nvidia, have backed Anthropic in a legal battle against the Trump administration after the government retaliated against Anthropic for refusing to allow its AI tools to be used for mass surveillance and autonomous weapons. The case, which centers on alleged violations of free speech and First Amendment rights, has drawn support from tech employees and former military officials, raising concerns about government overreach and its chilling effect on the technology sector.
Several major US technology companies have rallied behind Anthropic in its legal battle against the Trump administration, following government retaliation after Anthropic refused to allow its AI tools to be used for mass surveillance and autonomous weapons. Microsoft, in particular, warned that the government’s actions could have “broad negative ramifications for the entire technology sector,” emphasizing that AI should not be used for domestic surveillance or to enable autonomous warfare.
A joint amicus brief supporting Anthropic was filed by the Chamber of Progress, a tech advocacy group representing companies like Google, Apple, Amazon, and Nvidia. The group expressed concern that the government’s actions threaten First Amendment protections and warned against punishing companies for their public speech. Notably, Meta (Facebook’s parent company) did not join the brief, having left the Chamber of Progress in 2025.
Anthropic’s lawsuit alleges that its free speech rights were violated after public criticism from President Trump and others, who accused the company of being “woke” and politically opposed to the administration. The amicus brief described the government’s labeling of Anthropic as a supply chain risk as a “potentially ruinous sanction” and warned that such actions could create a culture of coercion and silence within the tech industry.
Additional support for Anthropic came from nearly 40 employees of OpenAI and Google, as well as two dozen former high-ranking US military officials. The military officials argued that the government’s actions could discourage investment in national security by making companies fear retaliation for voicing disagreement. The tech industry’s support for Anthropic is notable given that many executives have previously supported and donated to Trump.
The dispute began when the Department of Defense allegedly pressured Anthropic to remove contract language prohibiting the use of its technology for surveillance and autonomous weapons. After Anthropic’s CEO, Dario Amodei, publicly refused to remove these guardrails, President Trump announced that Anthropic’s tools would be removed from government use, and the company was designated a supply chain risk. Legal and free speech advocates warn that this case could set a precedent for future clashes between tech companies and the government over issues of free expression and national security.
