Where do I claim Google is doing it intentionally to help government intrusion? The paragraph about law enforcement is only meant as an example of how signing can be used against you. The point there is that it doesn't even need to be Google's intention and requires no direct assistance from them. I'm sure Google has a valid legitimate use of this data somewhere, but why it ends up in end-user XMPP clients is a mystery to me. If Google's aim is to avoid enterprise networks messing with the message, then Google should document somewhere how to verify the signature.
