Do any of these "decentralized" and "end to end" encryption communication systems actually solve the fundamental problem which is that you have to trust the person you're communicating with to not give up the content of the messages they've sent and received. People's telegram and signal comms are always showing up in subpoenas because someone unlocks their phone for the feds. I guess what I'm thinking here is that there's nothing about this that is any better than pgp emails, and i'm not sure i understand why these forms of communication are flourishing when they seem to offer little real protection against a motivated state adversary who doesn't need to attack the system if they can just ask someone for the keys
