@William: What you describe would be a perfectly fine strategy for a "roality free" (or CC0/public domain site) to maximize potential commissions; although one might as well argue that restricting certain commercial uses unless getting paid is an equally viable strategy.

But I feel OGA wasn't created solely for the purpose of maximizing the art commisions of its users!

Sure as you have pointed out it helps funding Free art also, but insisting on certain principles and trading off some (mostly theoretical) profit for it is what I believe one of the core ideas of OGA. At least that is what distinguishes it from other "free assets" sites.

@Others: Usage rights of stuff posted on OGA are already very welcoming of new users and commercial use (notice how NC isn't even an option; a good thing in my opinion). It is also not about trading off between the "perfect" and "still good enough" solutions.

I see it as a question of preserving the most minimal rights of the creators and users/customers.

It's amazing how even those basic right are slowly taken away from us by the likes of Apple and people still make excuses and justifing it. I guess I am an old fart, but as little as 20 years ago, people would have been in utter disbelief about the usage conditions people acept these days without question.
