The EFF warns that cloud‑based trusted execution environments (TEEs) do not provide the same privacy guarantees as end‑to‑end encryption. When AI features offload message data to TEEs, the content leaves the device and is exposed to unencrypted third‑party servers. Users and developers should avoid automatic data transfers to TEEs to preserve privacy.
Why it matters: The article highlights that relying on TEEs for AI processing undermines the privacy of secure messaging, urging user control and developer restraint.
