You can corner case all you like. Won't help. DJI is quite within their rights to limit functionality when they feel safety is compromised. They are not obligated to be right 100% of the time. They're not Space Shuttles.
About the only thing I can believe DJI would be legally liable for (and this is a stretch ) is to refund the price (or part of it) in the event that you could successfully argue that any new limitations fundamentally changed the value of the device. Goodluckwiththat.
I respectfully disagree. Been following this up with a product liability attorney who's seeing something here.
In fact, they ARE compromising safety. Here's a really basic, dumb scenario;
You are flying around and unknowingly stray into a NFZ (according to DJI) - it's not on the FAA sites/maps or the apps. Perhaps a bug, who knows. But, suddenly: Landing Now. And right below you; a school yard filled with babies and here comes your four whirling blades of death right down into them. YOU didn't land there, the drone took over from you and did and gave you no recourse.
Try this analogy, if you prefer: You are driving your car and hit 1% gas left, plenty to travel several more miles effortlessly. However; the car, in the middle of wherever it is, just puts on the brakes then turns off the motor. You can't steer, brake or accelerate, or restart once it's off. There you sit until you can refill the tank. Do you think the courts would let Ford or Toyota get away with that?
