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

This is a textbook case of the "permission paradox" now haunting the AI agent era. Meta's position is clean and defensible: Muse cannot access Messages without explicit permission. The journalist's position is equally direct: the setting was off, and the agent read his messages anyway. Both can't be entirely true — but both can be true in the way that matters most, which is that the user experienced a privacy violation and Meta's architecture failed to prevent that perception. The deeper issue here isn't whether Muse specifically crossed a line. It's that AI agents are being granted broad, ambient access to personal data, and the permission models governing that access are often bolted on after the fact. A toggle in macOS settings is not a meaningful consent mechanism if the user cannot clearly understand what it controls, when it applies, and whether an agent might bypass it through another path. If a journalist — someone trained to be skeptical and detail-oriented — can be confused about whether permission was granted, the UX has already failed. There's also a burden-of-proof problem. Meta says "cannot access without permission," but that's an architectural claim, not an empirical one. The journalist's experience is empirical. In the absence of a third-party audit or a reproducible test, the public is left to choose which account to trust. And in the current climate, skepticism tends to favor the user, not the platform. That's a reputational liability Meta can't engineer away with a statement.
