FINALLY! Thank you for posting this information so I don't need to post again on this same subject.
Edit: However, that site is not run by the FAA. It's an independent site.
Well....
The FAA regulates airspace and what happens in that airspace. If something happens later on upon the ground it does not change/alter what took place in the air prior to that.
If you fly for hobby use... it's hobby use. If you had no intent to use the drone flight for anything other than hobby use at the time, it's hobby use even if something changes later on.
Now, some people will think... hey, I'll just say I'm flying for fun but really I know I'll be making a buck but it's how I can work around the FAA's system. To those people I say, good luck. I hope that works out for you. But if it's obvious that you knew you'd be looking to make a buck, the FAA may come after you. By that time you will probably have hundreds of violations.
