The YouTube example was explained to me that the owner is being paid for the videos as that’s his “brand.” His name is on them and that’s what he does. He (or she) is not being paid to fly the plane, but rather is being paid for his video content.
Another example was that you’re flying over a raging flood, take photos of it then sell them to the newspaper. The newspaper is paying for the photos, not for the pilot to fly the plane. If aerial photography is what you do, then you can be paid for it, without an AOC.
Channel X was explained in exactly the same way.
That isn't a plain reading of the law. It even specifically states that a third party cannot have you take aerial photos (say for free to build hours) then they receive remuneration for the photos or footage. The medium is irrelevant. Whether its a Movie, YouTube, or your own Art exhibition if anyone is getting paid you need an AOC.
Reality is now professional photography will be done in a Drone bypassing all this but that's another story.
