Airlines are basically as stupid and greedy as telcos. If it were up to them, GA aircraft, UAVs, model aircraft and basically anything that wasn't military or an airliner would be banned. It has strong analogs in telcos swallowing up large amounts of spectrum "cause muh 5 gee" and just squatting on it. I'm sure safety would be in the shitter too if the FAA was less watchful (not to say it's sufficiently aggressive on the big players today).

Every one of their pilots learned to fly in a GA or military aircraft, with the vast majority being GA.
