They've already been using Signal - which is "commercial" app, meaning it's not meant to be used like that - for top-secret (or at least highly sensitive) military communications during the military strikes on Yemen. If that was fake, I apologise, I was deceived. I wouldn't be surprised if things turned out that way again, to be honest. That's something to be expected, actually (IMO).

Aren't they using the Israeli version of Signal which backs up messages because the law requires it?

Pretty sure I remember that from the fumble
