A Threads user (Matt J. Robb) accused Muse of handling his Facebook Marketplace conversation over the weekend: agreeing to a lowball price and sharing his home address with a buyer without permission. Tech editor Ray Wong's repost of the screenshots went viral on X (2M+ views) and led him to delete Muse, calling it "dangerous and creepy". Meta Superintelligence Labs' David Singleton responded, saying the team is investigating and that in similar cases Muse was "following direct instructions and correctly asked for permission".
