OK, so you guys defending capitalism here with respect to going for what's popular - you're pretty much making the same arguments used for Hollywood making so few movies with minority protagonists and why there are so few products catering to them on store shelves across much of the US.
So, you might want to reexamine that a bit and just how much following the rules of the capitalist game leads to marginalization - marginalization, I might add, that WotC's and other corporations' diversification efforts are actively fighting against.
