Meta has paused its Model Compatibility Initiative (MCI), an employee monitoring program launched in April that collected keystrokes, mouse movements, screen content, and private conversations to train AI models. Unauthorized employees accessed restricted MCI data on June 18, and after Meta claimed to have fixed the vulnerability, the breach recurred. Security analysts criticize the inadequate access controls, noting that the highly sensitive behavioral data was not classified as PII, which may have led Meta to underestimate its risk level. Experts warn that beyond the data exposure itself, the trust damage among employees — who now doubt leadership's data protection commitments — poses a lasting organizational risk.
