> And honestly, E2EE's strict definition (messages between user 1 and user 2 cannot be decrypted by message platform)... Is unambiguously possible for chatGPT. It's just utterly pointless when user2 happens to also be the message platform.
This is basically the whole thrust of Apple's Private Cloud Compute architecture. It is possible to build a system that prevents user2 from reading the chats, but it's not clear that most companies want to work within those restrictions.
> If you message support for $chat_platform (if there is such a thing) do you expect them to be unable to read the messages?
If they marketed it as end-to-end encrypted? 100%, unambiguously, yes. And certainly not without I, as the user, granting them access permissions to do so.
