I don't know any of the players but I'd bet they're licensed amateur radio operators.
I will say in Northern Colorado a LOT of the people involved in the MeshCore are HAMs.
Speaking as a person who works professionally in fcc part 101 licensed point to point microwave systems carrying IP data, I have less than zero patience for the BS and shenanigans of analog ham radio enthusiasts.
They always want to posture as if they'll be some critical service every emergency responder comes running to in a major disaster and it rarely if ever happens.
In the interests of not reinventing the wheel, you can see here in the same thread the comment from many other posters about the problems that they have with the behavior, attitude, and perspective of many ham radio operators.
Actually the opposite, tons of ppl in the meshtastic community (Discord) berate amateur radio operators. I stopped even discussing the subject because of how much derision I observed or was subjected to. Lots of insults and nasty jokes in passing as soon as the topic even comes up whatsoever. Kinda like your post, actually - offhanded derogatory remarks about an entire group of people solely because of the hobby they're involved in.
