Couple of minor nits:
1. Some rando on X saying "OMG! I infiltrated a lefty signal group" doesn't mean said rando actually did infiltrate a signal group.
2. Signal was not the app Hegseth, et al. used. They used TM SGNL, which is a fork of Signal. But that's a minor nit.
3. Encryption is not the same thing as authentication. And authentication is somewhat meaningless if you let everyone into your encrypted group chat.
Anyone organizing your neighborhood and events keep inner circle chats to only people you have personally vetted and use a new group chat for every event/topic and delete the groups for past events.
Be mindful of what you share in a big group chat where you don’t know everyone
