Meta employees across multiple U.S. offices have launched a protest against an internal tool that tracks mouse movements and keystrokes to train AI models. Flyers distributed in various office locations urge staff to sign a petition demanding the withdrawal of the Model Capability Initiative, which captures data from hundreds of applications, including Google and LinkedIn. Employees have expressed concerns about privacy, fearing exposure of sensitive information. The protest comes amid heightened tensions as Meta plans to lay off 8,000 employees on May 20 as part of an efficiency drive linked to AI investments. The petition against the Model Capability Initiative marks the first coordinated public action by U.S. staff, highlighting growing internal opposition since the tool's rollout in April. Meanwhile, Meta employees in the UK are organizing with a union to address similar concerns.
