I'll be blunt. This is self-serving propaganda. Ex-post rationalization is not unique here, but it is evident. Guys who fly want to justify their actions and offer up every excuse they can think of: comparison to manned flights ("would you shoot down a helicopter?"), FAA and airspace rules ("you don't own the air over your property"), claims of technology limitations ("we can't see you, the camera is wide angle"), etc. The end of this video, comparing the choice of sharing personal information ("Facebook") to the absence of choice when some neighbor is flying over your house is just ridiculous.
A sense of entitlement combined with myriad excuses is not going to endear the "drone" flying community to the rest of the world. Furthermore, being "right" (e.g., with respect to airspace rules or limitations) is not enough.
Do the decent thing and don't fly over private space without permission. Certainly don't fly over a residence at low enough altitude to be shot with a shotgun. By the way, for those not familiar, the effective reach of birdshot is very limited. If your drone can be taken down by a shotgun then it's guaranteed to be relatively close to the shooter (well within 100 yards, with 50 yards as a practical range).
