The rapid response networks people organize to defend their communities have undergone a whirlwind evolution to keep up with ever-shifting ICE tactics.
The single point of vulnerability is Signal. If something happens to Signal, one should be ready to apply Telegram or Tox. If connectivity is disrupted, one should have a plan of switching to Briar or other meshes (wifi + backbone of radio modems).
Besides XMPP, Deltachat is an interesting option since it uses email as its backend protocol, which makes it very difficult for a state actor to block without also blocking all regular email, which isn’t economically viable to do for any length of time.
There is also the option of Session and similar apps that don’t use mail or phone number. From my experience with it, it was super easy to use and even tho at first it was quite buggy, but the devs were constantly improving it. I haven’t used it for a couple of years now, and was great then for the way we used it - but I wouldn’t be surprised if it is even better now. I mean, I hope!
