If DJI do get retro-banned in the states, all protest and opposition fails and it becomes illegal to fly them, then I wonder how long it will be before someone knocks up some 3rd party firmware for DJI UAVs that disables compulsory updates, turns off remote ID, and includes a raft of other avoidance measures allowing people to continue flying undetected, spoof ID'd and unlogged ?
If there was enough level of civil disobedience and people using stealth, counter-measures, and alternative firmware in their drones those law-makers could find themselves in the sort of situation where the very rules they have created (and have remained almost entirely ineffective against true bad actors) merely drive thousands of previously law-abiding pilots underground as well, or move them sideways into FPV, where rules are much harder to enforce and pilots much harder to find !
Of course I couldn't possibly condone or encourage this sort of behaviour, but as that dinosaur documentary I saw a while back taught me, 'Life will find a way !' and so might pilots...
