I'll bite - with my reasoning for added value:
1 - AOC
2 - No AOC (under CAR), AOC for Aeromed work under new CASR's - aerial work certificate for everything else.
3 - No AOC (<6 pax), AOC if more than 6 pax
4 - AOC
5 - No AOC - youtube is by its own definition about sharing information, the photographer has no control (when where how) over people paying to advertise on his site. The goods for sale are essentially the spaces between his videos not the videos themselves.
6 - AOC - the photographers product is access to his videos he owns and controls the product.
7 - AOC
8 - AOC
9 - AOC
10 - AOC
