Microsoft revokes internal Claude Code licenses for Copilot CLI

microsoft is terminating internal licenses for anthropic's claude code, forcing teams like experiences and devices to migrate to the less-developed github copilot cli by late june. while the company officially claims this shift allows for better product integration and security, sources indicate the primary motivation is reducing operating expenses before the june 30 fiscal year-end. developers reportedly preferred claude code over copilot cli, creating internal competition for microsoft's own product. this transition pressures the github team to rapidly close the feature gap to maintain developer productivity.
