How are they analyzing network traffic with Signal? It's encrypted. And why does it matter if they know you're sending a message? Literally everyone using Signal is sending a message.

It's just a secure messaging app with a direct line to Guardian journalists. How to use 911 or special numbers when you're not feeling well.
