OK, I understand your point of view.
I can share with you my own experience.
I have participated to the competition for a couple years and I could see my pictures in photo articles telling about the competition and on the competition's website, like any other competition does, and that's just fine with me.
I suppose you know Keri Wilks, Arturo Telle and many other of the competition happy winners. They never had to complain about anything.
I personally think this competition is making a great honor to UW photography by offering so many and huge prizes as never seen anywhere else.
Moreover, David Pilosof, competition organizer, used to be one of the most famous UW photographer many years ago and he knows everything about pictures and rights. He's not interested to grab in any way your pictures, but just promote this fabulous festival.
So take your chance, you still can win $10,000 along with 3 weeks in Papua New Guinea and some more other great prizes
Good luck!
