In response to the last one, hope i'm not off-base
To the person who couldn't see why that would be detrimental, the point is that he's making money. The people who MADE those things are NOT making money. It's not a matter of him showing their art. It's the fact that he's exploiting it. It's illegal. It's unethical. It's being a jackass.
And it's about as right as killing puppies. You don't like killing puppise, do you? Think of the puppies.
That is all. Props to Lemon Demon and the rest.
