I dont see the argument posed here. If a user sends a new message to 2nd user, and 2nd user forwards the message to a government agent, and agent asks for the origin of the message, there is a way to both encrypt the message and trace it. It's called convergent encryption. And I thought this was how whatsapp was tracking messages that were forwarded multiple times. By checking their base hash.

FYI convergent encryption is hashing the original message, using hash as key to encrypt message, and sending hash key to user via 2nd encryption. The hash encrypted message will generate a second hash which will be used to track the spread of a message.

Interesting, do you have resources to learn more on that?
