Let’s think about this …a private enterprise is using a Federally funded system (ADSB) to collect fees from users of a Federally funded airport.
In terms of “a lot of owners removing” the system. Its called civil disobedience. A very large number of owners remove or turn off the system, and the number is so large that it cripples the system, and the “powers that be” have no choice but to listen to the concerns, and perhaps modify the system (or take other punative action against airports) to prevent fees being assessed based on system information.
