FAA spokesperson Les Dorr was quoted in the article as saying that it was possible the reason the FAA decided to send the warning letter was because several of his videos involve flying near and overhead of non-participants. Depending on the UAV, that could present a significant danger to them, especially if he lost control of it. The FAA letter makes reference to this at the bottom of page one. Flying in that manner is against the regulations of the AMA. I suspect that the reason the FAA letter even mentions the word "commercial" is because there are basically three ways to fly UAV that the FAA considers legal: 1. Government -- I don't know much about this one. 2. Commercial -- requires the appropriate licenses and permits from the FAA with strict guidelines on the restrictions for any given flight. 3. Hobby -- The FAA Modernization and Reform Act of 2012 has a few specific requirements to be eligible to fly as a Hobbyist. The first is that the flight does not result in any revenue (with a few very small and fuzzy exemptions) and the second is "the aircraft is operated in accordance with a community-based set of safety guidelines and within the programming of a nationwide community-based organization" Since he was flying in a way that would not be in accordance to the AMA's regulations, and he isn't flying as an authorized government agent, the FAA is likely putting him in the only remaining category, commercial. All that said, I despise the way the FAA is treating UAV operators. Everything from their absurd interpretations of the FAA Modernization and Reform Act of 2012 to their glacial pace at actually making commercial flights a reasonable possibility.
