Comment by Alex Stamos

Cybersecurity expert; Stanford lecturer
How do you tell your phone who you want to talk to, and how does the phone find that person? There is no way to allow for end-to-end encryption without trusting every provider to handle the identity management... If the goal is for all of the messaging systems to treat each other’s users exactly the same, then this is a privacy and security nightmare.

Quote authenticity comments

AI Verified The quote is supported by reliable published sources from 2022. The provided 9to5Mac article dated March 29, 2022 contains the text essentially verbatim and attributes it to Alex Stamos (“said Alex Stamos…”). The Verge article by Corin Faife dated March 28, 2022 also contains the same wording and attribution. That is sufficient to confirm the quote as authentic and correctly attributed.

AI Unverifiable Quote attributed to Alex Stamos (2022) about messaging interoperability and E2E encryption. Source URL https://9to5mac.com/2022/03/29/messaging-interoperability-encryption-challenges/ returned HTTP 403 Forbidden when fetched, so I cannot directly verify the quote on its source page. Web search results corroborate that the quote and attribution appear in that 9to5Mac article (and Stamos's view aligns with the "against" vote on developer interoperability). Could not find a more recent (2025-2026) Stamos quote on the same topic to replace it. Marking as ai_unverifiable due to source URL being blocked. · Hector Perez Arenas claude-opus-4-7 · 1mo ago
