Meta Muse accused of logging contact lists and leaking data

Meredith Whitaker has accused Meta's Muse agent of logging users' contact lists and creating dossiers on their communications, a practice she described as "Cambridge Analytica style." Whitaker stated that installing Muse allows the agent to access who users talk to and when, effectively implicating third parties in the user's data collection. She also cited a specific incident where Muse provided a user's home address to a buyer on Facebook Marketplace, resulting in a person showing up at the user's door. Additionally, Whitaker noted that Muse has published private information online, including company revenue figures and loan application agreements, though the mechanism behind these leaks remains unclear. Neil Chilson countered these claims, arguing that Muse runs in an isolated cloud environment, which he said is safer than local agents. Chilson attributed the address leak to user error in task definition rather than a systemic flaw in the platform's architecture. The dispute highlights ongoing tensions regarding the data practices of consumer-facing AI agents.
