Re: Any idea?
I haven't got a drone but my guess is that the geofences are arbitrary and don't make sense? Like you want to fly your drone in the park but the council's head of estate management works in a shed there and someone has geofenced it as a sensitive government building.
I really doubt hobbyists are going to go Aha now I can disable the Heathrow zone, not with the brownstorm that would mean they had to deal with.
