Signal President Criticizes OS-Level AI Agents Over Privacy Risks
At the TechBBQ conference in Copenhagen, Signal President Meredith Whittaker warned that upcoming OS-level AI assistants, like Apple's Siri and Google's Gemini, present an existential threat to privacy. These integrated agents bypass end-to-end encryption by capturing screen content, such as screenshots, to process data via external large language models (LLMs). Whittaker linked the current AI boom to the ad-supported, mass-surveillance business models established in the 1990s, arguing that Big Tech's economic structures prevent true privacy. Without platform-level opt-out controls from Apple, Google, or Microsoft, she warned that privacy-focused apps like Signal may struggle to guarantee integrity within one to two years. Whittaker reaffirmed Signal's commitment to user trust, noting that the nonprofit requires approximately $50 million annually to operate, funded entirely by donations to resist commercial revenue and data monetization pressures.
Whittaker highlights a major technical vulnerability where operating-system-level AI agents capture screen data, bypassing application-level end-to-end encryption. This presents a critical privacy debate for the entire mobile application ecosystem.

Signal Chief Warns AI Chatbots Pose Security Risk
Meredith Whittaker, president of the Signal Foundation, warned in a Bloomberg interview that widespread use of AI chatbots and agentic assistants poses significant security risks. She says Signal deliberately avoids integrating chatbots or AI features because such tools could undermine end-to-end encryption and expose plaintext if an agent is integrated at the OS level. Whittaker described using ChatGPT only for minor tasks like formatting documents and advised users not to treat chatbots as conscious companions. She referenced Microsoft AI chief Mustafa Suleyman’s vision for Copilot handling tasks like holiday shopping—raising concerns that such functionality would require extensive access to family chats, calendars, payment data and other personal systems. Whittaker also warned that control of major operating systems by Microsoft, Google and Apple concentrates power to make decisions that could harm collective cybersecurity.
Signal President: AI Chatbots Are Not Your Friends
Signal President Meredith Whittaker warned in a Bloomberg interview, reported by TechCrunch on June 20, 2026, that AI chatbots (e.g., ChatGPT, Claude) are not conscious or sentient and cautioned against treating them as friends. Whittaker said she uses AI tools sparingly for tasks like formatting but avoids relying on them for thinking or drafting, because their responses reflect averaged existing content. She criticized scenarios where assistants like Microsoft Copilot would gain pervasive access to personal accounts and devices — describing such access (credit card, browser, Signal messages, calendar) as effectively creating a backdoor into private communications. The remarks frame privacy and access concerns around conversational AI as material considerations for messaging platforms and user data protection.
Instinct AI assistant raises privacy and security concerns
Instinct, a San Francisco startup building a messaging-based personal AI assistant, is in private testing but has drawn praise for its capabilities and criticism over privacy and security. Testers reported that the assistant connects to email, messaging, calendar, device audio, location and screen data, can act on users' behalf, and that its Terms of Service grant a broad “perpetual and irrevocable” license to user materials (including for model training). Reported issues include retained plain-text email data after disconnect, inability to delete some records, sending emails without explicit confirmation, and susceptibility to phishing. The startup is led by Noah Shinn, reportedly operated by Spear Street Technology, and has drawn investment from Kleiner Perkins and Conviction; TechCrunch reports the company is operating in stealth. Instinct’s team has not publicly responded to the complaints cited in the article.
