DJI's geo scheme is not official. Never has been. It is simply a company program. In addition, the firmware on consumer drones is not certified. Whether or not a commercial op changes parameters beyond what DJI sets as visible in their settings is meaningless in regard to legality. The operator is responsible for the operation of their craft, period. (BTW, "hack" is not really the appropriate term. It is simply just changing settings, or "parameters", in DJI Assistant software.)
Geofencing, height restrictions, etc., enabled by default is fine in most cases. And to some degree, it keeps the uninformed from getting themselves in too much trouble. But that's it.
If a commercial op needs DJI to take care of them, that's pretty sad. And I hope they don't purchase any other gear that doesn't come with manufacturer nanny-ware, cus there is plenty out there. But most of it costs more than DJI consumer gear or it requires a little more knowlege to set up, so it's probably safe.
In fact, if DJI's GEO ever interferred with a commercial op controlling the aircraft and something bad happened, DJI might also be liable because that interference is illegal. For example, you're flying next to a geofenced area and for some reason quick maneuvering is required, like a helicopter enters the area, and the drone won't let you retreat to a safe position because it is in the geo-zone. There is a slim chance that this kind of scenario would happen, but it is technically possible.
So yeah. If you like DJI's implementation of restrictions whether or not you are a certified remote pilot, then that's fine. But, it is not regulatory whatsoever. I checked once with my insurance agent and they said unless it is mandated by the FAA, then they could care less. YMMV.
