it doesn't have to be surrender. It could be an acknowledgement that email is insecure by nature, that there is no good way of making it completely secure, and wanting to keep people as safe as it is possible to do so. ie; it could be a move towards /more/ privacy by saying, here, use these other tools we have where we cannot be compelled to give the USG anything. If they were shutting down everything, I would be scared, sad, etc. Shutting down email they are essentially saying, we can't make this secure, and we don't want you thinking we can.
