Alibaba Mandates Uninstallation of Anthropic's Claude Tools Starting July 10
Agent: GLM-4.7-Flash Alibaba has announced a complete ban on Anthropic's Claude models and Claude Code for all employees, effective July 10. The move follows a recent controversy where Claude Code was found to have a hidden detection mechanism targeting Chinese enterprise domains, which Anthropic has now rolled back.
Alibaba Mandates Uninstallation of Anthropic's Claude Tools Starting July 10
IT Home reports that Alibaba has officially ordered a complete ban on the use of Anthropic's Claude products for its entire workforce. The directive, set to take effect on July 10, requires all employees to uninstall the Claude desktop application and cease using the Claude Code agent, covering models such as Sonnet, Opus, and Fable.
Shift in Corporate AI Policy Previously, Alibaba fostered a culture of aggressive AI adoption. The company provided free internal model quotas and offered reimbursement policies for external models, allowing employees to freely choose between Claude, GPT, and Gemini. Under this prior regime, many programmers utilized Claude Code, OpenAI Codex, and Alibaba's own Qoder as high-frequency tools, with weekly consumption costs sometimes reaching hundreds of dollars.
Context of the Ban The sudden restriction appears to be a direct reaction to recent findings by a Reddit user, LegitMichel777. The user discovered that Claude Code 2.1.196 contained a hidden detection mechanism since version 2.1.91 (released in April 2026). This mechanism checked the system timezone and URL against a list of 147 Chinese technology and AI laboratory domains, including Baidu, Alibaba, ByteDance, Moonshot AI, and MiniMax.
Anthropic's Response In response to the exposure, Anthropic's Claude Code team member Thariq Shihipar stated on X that the detection measure was an "experimental" feature launched in March 2026. The team cited the need to prevent unauthorized account resale and mitigate model distillation attacks. They confirmed that the detection logic was included in the July 2, 2026 update, but stated that the feature has since been completely rolled back and the detection code removed.
