Meta disputes claim that Muse read a user’s private messages without permission

Following Inc. columnist Jason Aten’s report that Muse read private messages without permission, Meta VP Andy Stone said on X that Messages integration is entirely opt-in and requires enabling both Full Disk Access and the Messages connector. Meta Superintelligence Labs exec David Singleton described three separate application- and macOS-level permission steps that he says can’t be circumvented even with a Muse bug.

Aten claimed Full Disk Access was off and that Muse blamed syncing device notifications. Singleton said the model’s explanation was wrong and pointed to Muse’s security architecture and bug bounty docs. The dispute lands as Muse sits atop App Store charts and Meta faces fresh reputational heat from a New Mexico Cambridge Analytica-related jury finding.

We’re not refereeing a he-said-permissions fight from the sidelines — we’re watching trust erode in real time.

If Meta’s architecture story is accurate, the UX still failed the moment a careful user believed Messages were read cold. If Aten’s notification-path theory holds, that’s a side channel Muse shouldn’t treat as chat history. Either way, cute agents die on consent clarity.

I’m watching whether Meta engages the reporter with logs instead of categorical impossibility claims. Useful personal AI needs forensic transparency when users feel violated.

We’ll keep Muse’s Marketplace address incident and this Messages dispute on the same board. Reputation is the product now.
