Meta pauses employee tracking program MCI after internal data leak exposes sensitive work records

Meta 员工监控项目暂停：企业内部训练数据正在把员工操作纳入采集范围

Meta launched MCI in April 2026 to record keystrokes, mouse movements, and screen content from employee computers for AI training. The program was paused in late June after a permissions misconfiguration exposed screen recordings, private chats, and performance data across the internal network. Over 1,600 employees signed a petition; the program had no opt-out. The pause was not driven by regulators or training failure—it was an internal security breach that broke employee trust. Zuckerberg framed it as a third-wave training data strategy: let models learn by watching smart people work. Execution failed on informed consent, data minimization, and access control.

Why it matters: Cross-source cluster (WIRED, Guardian, BBC, Business Insider) with high fact density. Capped below 85 because it's a corporate governance incident, not a model/product release—limited direct technical takeaway for AI practitioners.
