Given that we're discussing the supply side of things, I think your example is backwards. But even if you changed it to competition for supplying the desire of yellow marbles, I still don't think it's relevant. It's certainly true that there's an incredible supply of cheap/free games on iOS (typically of very low quality, or chock-full of F2P mechanics or ads). But there's a very low supply of high-quality serious games being sold for more-than-a-cup-of-coffee prices. I think there's certainly a market for those games, the problem is just that you can't rely on the App Store for discovery (but you never really could do that anyway). So it seems the real problem is just that Jeff Vogel doesn't know how to market his stuff, and rather than actually figuring it out, or, heck, hiring someone else to do it for him, he's just giving up on the market entirely. Which is a real shame.
