I'm ignorant of mesh technologies, but can somebody explain to me why they are using MQTT in their stack? Topics and pub-sub over TCP doesn't sound like a mesh-y kind of thing. Does it work well in this context?

The mesh isn't doing MQTT or TCP. They're using MQTT to bridge between meshes, with mesh nodes that have an internet connection or are paired to a smartphone with an internet connection relaying mesh traffic with an MQTT server.

MQTT is used for map reporting, and sometimes as a "fallback" or to connect distant meshes.

Also very good way to instantly spend all your air time. Remember, legally you can only transmit at something like 10% of time. In some bands even less, afaik.
