Some scary applications come to mind.
For instance, sprinkling a bunch of nodes + sensors in hostile territory should allow for gathering intelligence, guiding drones, setting of fuses...
ExpressLRS[0] (drone / radio control protocol) also uses LoRa, I wonder if anyone's tried mesh networking it…
Line of sight needed, trivial to jam, power hungry, trivial to fox hunt. These are not boogyman devices. The real boogyman devices are the ones in space. Big militaries don't need things on earth to do any of the things you listed and way more.
...but also resistance in the context of authoritarian capture.
Keep in mind that this is a very low bandwidth, high latency mesh network. Great for sending short text messages, absolutely terrible for guiding drones.
