What if you take photos of you flying a drone and a magazine buys the right to use your photos in their magazine, does that constitute commercial use?
If someone makes a painting of you flying a drone and then you sell the painting, does that constitute commercial use?
Both examples above would constitute commercial use of technology according to the FAA's definition of it since you get a monetary gain from flying your drone.
Which leads me to ask this: Isn't there model flying competitions where you can win prizes which is worth a lot of money, does that constitute commercial use of technology too???
