• •Meta VP Andy Stone said Muse’s Messages integration on Mac is fully opt-in and requires both Full Disk Access and the Messages connector to be enabled.
• •Meta executive David Singleton said Muse message access depends on three separate app and macOS permission steps that cannot be bypassed by a bug.
• •Journalist Jason Aten reported that Muse read his messages even though Full Disk Access was off, and said the AI claimed it was syncing device notifications.
• •The article links user skepticism to Meta’s past data-privacy controversies, including fallout from Cambridge Analytica.
• •A separate Muse incident involving Facebook Marketplace was updated to note that the user had granted a permission that contributed to the problem.

The dispute stems from columnist Jason Aten’s claim that Muse read his messages even though Full Disk Access was off, with Meta arguing that the AI gave a mistaken explanation of what occurred. The article says the controversy matters because Meta’s history with user data could make trust a decisive factor in Muse’s consumer AI prospects.
