It is absolutely insane, considering they have SCIF devices / rooms but also the option of "not using off the shelf" shit like Signal and using a phone number. But here they are.
Hell, they could even use something like Briar / Matrix / whatever that is decentralised/does not require a phone number unlike Signal but instead they sent emotes, and classified information detrimental to US citizens over a centralised (third party) platform. Literally, insane.
It's like someone else said - I went back and dug a little on old.reddit (RIP r/America) and there's for some reason its "not being shared" and actually, neutered?
Maybe I'm just a sucker for popcorn but it smells like it shit, it usually is 💩
