To play devil's advocate here, he does have certain point.
I do graphic design work as well, and it's funny how people just expect me to "whip up" designs and not expect to pay for them, like I do all of this just for sh#ts and giggles or something. I told a recent client that this is a business, and they stand to earn a profit from my work, and I expect to be paid. When I quoted a price, they suddenly didn't need as much design work as originally thought.
It's darn hard being an artist in the digital age. We can't publish our work without fear of someone else ripping it off. Facebook provides great exposure, but at the same time, you can't protect yourself much either. Getty Images/iStockPhoto/others are the death of stock photography and should be outlawed in my opinion.
