The rush to bring a product to market overlooked security?
No surprises there.
On a similar note it's probably about time encryption was introduced as a standard to the radio control hobby market, because it's apparently fairly easy to hijack someone's drone if you have the right kit with a bit of knowledge, and it wouldn't surprise me if someone decides they can make some money selling an easy to use drone hijacking device.
There would be a danger it's a run-of-the-mill ~1kg camera drone being operated in the vicinity of pedestrians (which it probably shouldn't be), but could be so much worse if the drone in question were a large hexacopter / octocopter capable of carrying cinema quality cameras that weighs many kilos and can cost 10's of thousands.
