What about the hot air balloons, ultralights, antique airplanes, hanggliders, skydivers, drones, birds, and mountains?
It is our airspace too and we were there first. Airlines and motorplanes need to do a better job of avoiding all of the stuff in the sky. And if you guys start advocating for limiting my ability to fly without a transponder than I am going to start advocating to limit your flying regardless of how powerful a ball roasting beeper you put in your gliders.

All we need is one glider-airliner collision and you can fully expect to be grounded until ADSB is installed in your glider. Gliders came very close to loosing their exemption for Mode C due to the non-fatal collision between a biz jet and a glider near Reno. It will not be "us guys" limiting your ability to fly, it will be the FAA. The economic reality is that it matters not a whit who "was there first". Airline safety will take priority over any other consideration.
