@matthew_d_green The solution to the problem posed in that piece is referenced in it: #FBI got #Signal messages when they had a legitimate reason to have them. End-to-end encryption stops mass surveillance, but clearly did not stop the Jan 6th investigations. I think its pretty clear that phones should be treated like one's house in terms of search and seizure. Courts can compel people to give info, and can compel people to unlock their phones. My guess is that's how FBI got info from Signal.
