Tech Workers Rally Behind Anthropic in Legal Battle with Defense Department
Over thirty employees from OpenAI and Google DeepMind submitted an amicus brief on Monday backing Anthropic’s legal challenge against the U.S. Defense Department, following the Pentagon’s controversial decision to classify the AI company as a supply chain security threat.
The court document, which includes the signature of Google DeepMind’s chief scientist Jeff Dean, condemns the government’s action as “an improper and arbitrary use of power that has serious ramifications for our industry.”
The controversy stems from the Pentagon’s recent classification of Anthropic as a supply chain risk—a designation typically applied to foreign adversaries—after the company declined to permit the Defense Department to utilize its artificial intelligence technology for domestic mass surveillance operations or autonomous weapons systems. Defense officials had maintained they should have unrestricted access to AI capabilities for any “lawful” military application without private contractor limitations.
The supportive brief appeared on court records shortly after Anthropic initiated dual lawsuits targeting the DOD and additional federal agencies. The timing coincided with the Pentagon’s immediate signing of an alternative contract with OpenAI following Anthropic’s designation, a decision that sparked internal protests among ChatGPT’s workforce.
In their legal submission, the tech employees argue that if the Pentagon found Anthropic’s contractual terms unsatisfactory, the appropriate response would have been to “simply canceled the contract and purchased the services of another leading AI company” rather than pursuing punitive measures.
The brief warns of broader implications for American technological leadership, stating that “this effort to punish one of the leading U.S. AI companies will undoubtedly have consequences for the United States’ industrial and scientific competitiveness in the field of artificial intelligence and beyond.” The filing further cautions that such actions “will chill open deliberation in our field about the risks and benefits of today’s AI systems.”
The document validates Anthropic’s ethical boundaries as reasonable safeguards requiring robust protective measures. The employees contend that absent comprehensive public legislation governing AI deployment, the contractual and technical limitations that developers establish serve as essential protection against potentially catastrophic misuse of artificial intelligence systems.
Many signatories to this court filing had previously endorsed public appeals in recent weeks demanding the Defense Department rescind its supply chain risk designation and urging their respective company leadership to stand with Anthropic in opposing unrestricted military AI access.
