> Yes but National Security Letters make that pointless
It seems ridiculous to use the term "national security letter" as opposed to "subpoena" in this context, there is no relevant distinction between the two when it comes to this subject. A pointless distraction.
> You can't encrypt away a legal obligation.
Of course you can't. But a subpoena (or a NSL, which is a subpoena) can only mandate you to provide information which you have within your control. It can not mandate you to procure information which you do not have within your control.
If you implement e2ee, customer chats are not within your control. There is no way to breach that with a subpoena. A subpoena can not force you to implement a backdoor or disable e2ee.
I believe we are in agreement. If you are a communication platform that implements e2ee then you provide the guarantee to users, backed by security researchers, that the government can't read their communications by getting a subpoena from the communication platform.
The problem with AI platforms is that they are also a party to the communication, therefore they can indeed be forced to reveal chats, and therefore it's not e2ee because defining e2ee that way would render the term without distinction.
