As
@tomokc said, he is one of the educated and responsible operators, that is aware of the big picture. I have a friend locally that is also an approved operator for hire. A process that required a considerable investment of resources to be legit. He has followed AC91-57, hired legal counsel to prepare his 333 exemption, etc.... Much like 135 vs 134.5, in the eyes of the uneducated, the only tangible difference between the two is paperwork. This is what my personal observation has been. For example, my friend and I will run in to people at the beach, mall, parks, wherever and see someone operating a UAV/ UAS/ drone/ quadcopter... So we will engage in conversation with the operator and ask questions using the submarine theory. "That's pretty cool, what model? How high does it go? What's the range? How long does the battery last?" They will almost always talk to a stranger. Just like any enthusiast would when talking about cars, motorcycles, firearms...The story is almost always the same: just bought it online, practiced it a few times in their yards, then printed some business cards on vistaprint, and now they are in business. During these conversations they'll say things that are appalling to pilots. No understanding of airspace, safety or general laws. They will say that they can fly it anywhere and film anything which is why I bring up the reasonable expectation of privacy. People have an expectation of privacy at their residences, place of business and other places. Flying a UAS over a fence and filming the backyard is no different than being a peeping Tom.
Creating a classification between various operations and types is not a bad thing. Recreational and professional or something similar is a good move. Even though both are remote controlled, there is a difference between a parkzone flyer and a DJI phantom or a 1/4 scale F-4 Phantom (

The advancement in technology is great, certainly has it's uses in the world, as well as misguided uses. Continued use with the lack of education or operational limitations (regulations...gasp!) is a recipe for disaster.
