I love the idea of the DoD using Matrix during what may turn out to be pretty eventful next few years.
Coast Guard: We are seeing unknown boats on the western sea board
Air Force: [Unable to decrypt message]
Army: [Unable to decrypt message]
NATO: [Unable to decrypt message]
Like, if your hacker trans girl or whatever is struggling to make your chat system exchange messages consistently and predictably, what hope does a single branch of defence with 200,000 troops have?
It's not like the DoD has hoarded all of the experts in this area from the rest of the world, likely quite the opposite
Well I'd frame it as a question of overhead and cost benefit.
E2EE necessarily carries administrative and resource overhead, and for one category of message that's completely worth the trade to keep secrets secret. But for other messages? Might as well leave them fairly exposed because you don't care that much about secrecy.
In this case, though, aren't they talking about real time voice communication? It's harder to do that over TLS through trusted servers.
