Yeah, the rich people thing was a sort of tangential aside.
My point as regards The Oatmeal is that the charity donation basically had nothing to do with the original issue. Again, I do think The Oatmeal is in the right, but what he has done is take a demand for $20,000 dollars of his money and said "Actually, I'm instead going to not spend any money and encourage a bunch of other people to give to charity."
I think the purpose of the charitable donation is to bring the court of public opinion to his side, and create more positive coverage of the situation. I can't help but wonder if the situation would have been different if he'd instead just said "Actually I'm just not going to give you the money." I think people would still be on his side, just not quite so loudly.
