Meta to US employees: We’re installing tracking software; later confirms private data leak

Meta has paused its controversial Model Capability Initiative (MCI), the AI tracking program that logged US employees’ keystrokes, mouse clicks, and screen activity, after an internal leak exposed sensitive data across 45,000 tables companywide. The breach laid bare private conversations, transcriptions, and performance data, confirming the exact security risk over 1,600 workers had warned about in a petition. Meta says it is now investigating the incident.
