Cows getting bigger,I generally agree with what you wrote but its not about
exercising their 'rights' in not talking to ATC
The whole system of how radiocommunication is conducted and the RT manual is not writen with gliders in mind and there is not an option of "no service required" which is what most of us request. Do you know that the Manual of Air Trafic Services has more writen in it about UFOs than gliders....
I do listen out and cringe at how much seemingly useless chat there is from transiting aircraft but that is what the system requires.
ADSB recievers are becoming affordable (less than £500) but the airlines seem reluctant to spend money on fitting ADSB, few Dash 8 have it for example and they are a common type outside controlled airspace.
EASA has made sure that fitting and maintaining transponders is prohibitively expensive
