What happened

The EFF explains that while trusted execution environments (TEEs) can protect data on cloud servers, they do not provide the same mathematical guarantees as end‑to‑end encryption. Sending message content to a TEE for AI processing creates a privacy risk, and developers should avoid automatic data exfiltration to TEEs.

  • Its status is announced. It is not law yet. Track it, but do not treat it as an obligation.
  • The article highlights a privacy risk where AI features offload encrypted messages to cloud TEEs, weakening end‑to‑end encryption protections.
