It's all a terrific load of horseshit, because the rage face and any other meme where it's combined by other people and spread is not really the created object of the originator, as much as it has become popular due to the uncoordinated but collaborative efforts of other internet users.
If the creator of "rage face" had come forward to stop other people from using his drawing without credit, it wouldn't have become popular. If it hadn't become popular, there would be no T-shirts.
There's a reasonable argument to be made that Hot Topic is making money, while the other collaborators were not making money; I suppose it's pretty difficult to assign a Creative Commons license to such a thing retroactively.
