That happens in every hobby. There's always people declaring themselves king of some hill and making things toxic. I've been in a lot of hobby organisations and it's always the same. In a commercial organisation these people get reported to HR and kicked out but volunteer orgs are much less likely to throw out someone who does a lot of work for free.

I've seen it in ham clubs, makerspaces, etc. It's just what happens. The best thing is having a rock solid code of conduct.

And yeah it's technically interesting though I really miss it being on the bleeding edge. That hasn't been the case for decades. The commercial world can send a gigabit per second to a phone but we're stuck with 9600 baud APRS (or 1200 even sometimes)
