Meta denies Muse AI read user's private messages
Meta is disputing a journalist's claim that its AI agent, Muse, read a user's private messages without permission. Inc. columnist Jason Aten reported that Muse accessed his messages without consent. Meta's VP of Communications, Andy Stone, stated on X that the Messages integration in the Muse app for Mac is entirely opt-in, requiring users to enable both Full Disk Access and the Messages connector. He emphasized that Muse cannot read messages unless the user performs these steps. David Singleton from Meta Superintelligence Labs provided a more technical explanation, detailing the multiple permission steps and macOS system-level protections. The company maintains that unauthorized access is impossible, attributing Aten's experience to a user misunderstanding. This controversy comes amid Meta's history of data privacy issues, including the Cambridge Analytica scandal and recent legal defeats.
This is a significant privacy and trust controversy involving a major tech platform (Meta) and its new AI agent, which could impact consumer trust in AI agents and lead to stricter scrutiny of AI data access permissions, affecting the broader AdTech ecosystem's reliance on AI and data handling.

Meta's Muse AI faces trust issues from users
TechCrunch's Equity podcast discusses Meta's new AI agent Muse, unveiled at Connect 2024. While the consumer-focused agent impressed with a party-trick-like feature (finding unclaimed funds), concerns were raised about its sustainability and user trust. The conversation highlights Meta's bet on consumer AI, contrasting with OpenAI and Anthropic's enterprise focus. A skeptic, Sean O'Kane, notes that despite some utility, the agent's reliance on sensitive data could clash with Meta's ad-driven business model, making users hesitant. The discussion also touches on Apple's Siri as a trusted alternative for handling such data.
Meta AI app notifies friends, raising privacy concerns
Meta released its Muse Spark AI model as part of an update to its AI efforts, and its Meta AI app — launched in April 2025 — has drawn attention for sending Instagram notifications that reveal which contacts are using the app. TechCrunch reports users received prominent Instagram alerts about friends’ Meta AI usage, causing embarrassment and raising questions about cross-app data sharing and consent. Appfigures data showed about 6.5 million downloads in the app’s first month and a half, and the app climbed to No. 5 on the U.S. App Store after a revamped chatbot (up from No. 57). The app previously featured a Discover feed that exposed published AI chat content; Meta has removed that feed. The article highlights concerns that Meta’s connected accounts (Instagram, Facebook, Meta AI) can surface sensitive usage signals and be used for ad targeting without explicit, clear user consent.
Meta Muse AI Calls May Use Humans, Raising Concerns
Meta's new AI agent, Muse, which is designed to make phone calls on behalf of users, may actually be using human call-center employees to complete these calls. Internal documents and employee communications seen by 404Media reveal that Meta has added a "layer of human agents" to handle calls when the AI cannot, despite marketing the feature as AI-driven. This has sparked criticism among Meta employees, who raise concerns about transparency, potential privacy issues (especially with sensitive data such as health information), and the risk of negative public perception if it is revealed that humans are stepping in. Meta claims that human agents are trained and that data remains secure, but employees remain skeptical.
