As controled as the airspace is by the US goverment by many different agencies, I can not see a fully independ group being allowed to run such a program. First near collision with a drone controled by Depin network will result in the end of the program or worse the total loss of a aircraft with souls on board will end in a law suit that will turn in to a shit show that will drag the whole program into court. Just look at the amount of legal actions lodged against Tesla and there still is a driver in the car seat. huge risk to take for such an expensive project, with a unknown reward outcome.
