I had a conversation with a cryptographer who worked for Wickr he says none of the DoD or other government agents he knew trusted Signal 🤔 - personally I use Signal with my mom or personal friends as like the bottom tier of security, because metadata is a real thing, they don’t have to actually know what you’re talking about. Just using a phone number itself tells you most everything feds need to know if they’re really after you.

if you actually want privacy use XMPP
