Yeah, xmpp is a great protocol, but everyone needs to be in the vicinity of the server. A mesh network (p2p) where every client also relays messages for other clients is better suited for this usecase. I think meshtastic is an open standard for this.
Briar is a valid alternative that works with phones, which most people already own.
Not the greatest idea to bring those to protests, though because of network surveillance attacks by police forces.
A meshtastic device would solve this problem.
