Yeesh. It's so catty on cc these days.
I just think that any artist or creative person should not try to compare or belittle another artist's work and say what they do is harder/more time consuming/more expensive/requires more talent than any other type of art. Not everyone can write, not everyone can decorate cakes, not everyone can be a photographer- each takes a different skill set, and unless you've been there, done that, you really have no idea what all goes in to their particular profession. The point is, we as artists (no matter what kind of art we do) should not be expected to give away our talent, time, blood, sweat, and tears for free, and asking us to do so is saying that our skill isn't worth anything. If it's not worth it to someone to pay me to do a cake, fine, they can go elsewhere. And I'll wait for someone who does value my work, thank ya very much.
If he sounds whiny, it's probably because he's been asked for freebies so many times that he's completely lost patience for it. I know the feeling.
