Preppers use it as a backup communication channel.

The scenarios are:

  1. Your country is invaded, and you are building a resistance.
  2. Your government becomes a dictatorship. You want to fight back.
  3. Natural disasters: the grid and mobile network are down. You want to organize and work together to help each other.

Meshtastic nicely blends into the existing IoT LoRa traffic. And give you some sort of invisibility.

Other scenarios are similar to ham radio - asking other dudes about the weather.

Or you are out in the mountains with spotty cell coverage and want to be able to send messages to other friends around you

Not everything prepper-like is for prepper-only usage

It's been a while but I can remember going to sport events where the local cell network could not cope with the traffic. Calls wouldn't connect and SMS were delayed.

These would also be handy in construction when you're deep in the bowels of a new building and can't get any reception whatsoever (cell, CB, etc.)

These are the scenarios I was looking for. Thank you.

The extreme event scenarios have pretty obvious applications but are also very rare.
