Defense tech companies are dropping Claude after Pentagon's Anthropic blacklist

The Trump administration blacklisted Anthropic (the company behind Claude, a popular AI assistant) and designated it a supply chain risk, causing defense contractors and tech companies to stop using Claude for defense work and switch to other AI models. Anthropic refused government demands for assurances that its AI would not be used for autonomous weapons or mass domestic surveillance, leading to the designation. The company argues the government lacks legal authority to restrict contractors from working with Anthropic for non-defense purposes, and says it may appeal through the legal system.
