I agree with you that it is likely that the FAA will leave hobbyist use alone for the time being, but it is clear that the entire drone concept, commercial and hobbyist, is getting a lot of attention and a lot of it is unflattering. It is a new and unsettled area of endeavor. It's not like the old days where the whole "drone" concept revolved around a bunch of geeky R/C pilots (I've been one for 40 years) getting together on a Sunday afternoon at their remote flying field. That was easy for the public to ignore. Now, you can take your drone off from your porch and spy on your neighbor sunbathing, chase their dog, or crash into their kid. Drone flyers have no standard-bearer organization. The only one that comes close to being our lobbying mouthpiece is the AMA, and they don't quite get it either (their requirement for a spotter for FPV, and major photography restrictions, for example). We're kind of on our own, no one to carry the sUAS banner at the lobbyist level, and likely only a few "incidents" away from really getting the attention of the FAA and causing them to have to shift their attention from just protecting the livelihood of commercial aerial photography pilots to addressing the perceived concerns (aided by the sensationalist media, who is not our friend) about the safety of the public and their protection from privacy intrusion. You know that there are many drone and other FPV pilots that will continue to bust the FAA Advisory Circular rules and ignore the AMA's safety code and recommendations in AMA Document 550.
If I was the CEO of GoPro getting ready to commit my company to a very expensive expansion of my business model, I'd be really thinking hard about those issues.
