Solid defense of the business, and I tend to agree with you. At the same though, you have to admit that with 5C and a bigger, broader apple, the apps that will win big will be apps that profit off volume and not individual sales.
Also, as an indie, I'm honestly not aiming for Candy Crush success. It might be possible to get in that vicinity like Tiny Wings, but it seems absurdly unlikely. I'm perfectly content to make a good living selling niche apps, and there is a big market available for it. Candy Crush and Clash of Clans aren't making all 5 billion Apple paid out last year.
