You may very well be right Dave. My theories are based upon unshakeable and inarguable daydreaming. I am an instrument-rated pilot, and my ideas are based partly on my experiences with FAA designated areas. What I would think is that the laws regarding drones are still evolving as we all know, and as usual, the laws and regulations are playing catch up with new technologies. I would guess that once companies begin to be concerned that drones could gather information they don't want gathered, the rules about flying over or near sensitive corporate (or other sites) may tighten up. While most drone operators are completely innocent, there are a few that might not be, and of course we'll all have to toe the line to ward off that tiny percentage. It's already happening, really. When drones first hit the stores, there were some vague rules that were applied from the RC fixed-wing gang, but not much really. As more and more drones hit the sky, then started causing problems, the laws tightened, and will probably continue to do so.
When I worked classified projects, it was well before toy drones were even a twinkle in some engineer's eye. One of the buildings I worked in was shaped like a square donut, with a courtyard in the middle for employees to relax during breaks and lunch. The patio was accessible only from the building, and the building was only accessible through tight security. Even then we were told, and there were signs on the doors leading to the patio reminding us, not to open classified information while on the patio. Something above us might be able to see the documents. There were even schedules posted on the doors of when Soviet satellites were going to be overhead. Of course, we engineers all went out at those times and gave the one-finger salute to the sky. Would have loved to see what the analysts in the Soviet Union thought about that.
That's a bit of a side story, but it does make one think what laws might be enacted for drones. Yup. There are already rules about where you can fly, but more will be done so companies can enact immediate remedies if they feel threatened.
