Their concern is safety, actually, which is why they've established the system they did. You just chose to see it as restriction.
It's not that your taking video with it that's their concern, if it was they'd try to regulate all video production, which they don't. They've come forward in some article (shortly after the youtube thing) where they said they don't understand commercial aspects very well, understandable it's not their job but you're flying an object into national airspace. At the current time, the only surefire way to make money is by using camera systems, whether you do photos or video, mapping, whatever...all uses cameras, that's why they are hitting that area.
Personally I have mixed feelings about the whole thing. Ground school is a definite must (much like a drivers ed course) but a pilots license isn't so far fetched either, it's not that expensive, if you've got money for an inspire...I mean for real, cost me about $4k for my sport license, was done in just about 2 weeks...while the actual learning flying didn't teach a lot about uavs, i think its more important you know how to communicate properly with atc, small airports, know the airspace regulations. I think it makes you more professional...so many people just think "hey, I'm gonna buy a drone, and shoot stuff for people and make money" I think taking a good flight instruction course, learning how to fly, and everything is going to make you stand out from the wackos you speak of, anyone of them can bring their phantom or inspire and show an instructor they can fly safely.
All in all, I don't mind the exemption at all...it really makes you know if you're gonna invest in this industry and a potential future or you're the type of guy that's "just gonna buy a drone to make some money"
