Anthropic refuses Pentagon's 'any lawful use' demand — Claude hits #1 on US App Store as users flood in

The Department of Defense demanded Anthropic remove two contract restrictions: a prohibition on using Claude for domestic mass surveillance, and a prohibition on powering fully autonomous weapons systems without human oversight. Defense Secretary Hegseth warned Anthropic that refusal would result in contract termination and designation as a national security risk. CEO Dario Amodei rejected the terms. The Trump administration then issued a government-wide order to phase out Anthropic technology, blacklisted the company as a supply chain risk, and barred defense contractors from working with them. Simultaneously, OpenAI signed a $200M Pentagon deal on February 27. Consumer backlash drove Claude to the #1 position in US App Store downloads, overtaking ChatGPT. Anthropic reported free signups up 60% since January, daily registrations tripled, and paid subscriptions more than doubled — all-time records broken daily that week. Anthropic subsequently sued the DoD.

This is the first major test of whether an AI company will hold a safety line under direct government pressure, and the consumer market responded decisively. The "QuitGPT" movement, 700+ Google and OpenAI employee signatures on a solidarity letter, and the App Store ranking together form a meaningful data point: a non-trivial segment of AI users will reward companies for standing on principle. The competitive implications are real — Anthropic gained subscriber momentum it couldn't have bought with marketing spend. OpenAI took reputational damage Sam Altman himself called "opportunistic and sloppy."
