Of course, the US government already has approved procedures and devices for secure communication, so senior official making up their own is reckless and unprofessional.
None of this is meant to excuse these officials for not authenticating everybody in that group or for using highly informal text messages to plan an airstrike of all things.
Ultimately there's no excuse for leaking information when you're at that level of government; I just feel like the app industry needs to take responsibility and fix several obvious, well-known and common UI issues.
Supposedly, it was the result of a helpful Apple feature getting the wrong phone number for one of the intended group participants. Then Signal cheerfully used that wrong phone number to add the reporter to the group.

If there are UI issues, they should be fixed because they are also annoying when planning somebody a surprise birthday party. (Or all the other stuff an encrypted chat app might be good for).

When it comes to practical cryptography, nobody is doing signing parties anyway. It's all TOFU unless someone forces people's hands, and when you force people to do security you can assume they won't bother checking if the QR code they're scanning is coming from a real app or a livestream of someone else's app, they just want to get the scanning done. The whole key scan thing is probably only of any use to people keeping contact after meeting with journalists.

That's all OK as far as it goes, but the root problem here is that a typical Signal user is made aware of none of this. Sure it's legit to take convenience over security, but it is not OK to leave this tradeoff completely unknown to the people affected.
