Well get used to the idea. If drone manufacturers don't build in some restrictions then the results will be that none of us will be flying. We have more than enough proof now that without restrictions bad things happen. I think DJI is being responsible in restricting where these units can be flown. Keep in mind though that the only way they will know where they are in space is if the GPS is used. So maybe it's as easy as just not flying in GPS mode to get around the restrictions. I'm not sure.
IMHO the only reason they put the restrictions in was to protect their market share. When the regulators clamp down on drones because of safety concerns that drones are a risk to air traffic and sensitive areas only drones that have in-built restrictions will be allowed to fly. 3DR are paying close attention to this as well, although I think they are coming up with some strategies that are a bit more intelligent as usual. Stay tuned... BTW, I'm also an advocate that drone flyers should adopt the good behaviour of the model aircraft sector and fly at designated fields under club rules with insurance. If you want to fly in public spaces you really should have some training and insurance. Also, the DJI restrictions are already global.
