What was wrong with the business model of The Daily? What business model should they have chosen? They were using (then brand new) subscription IAPs in the App Store, which were designed as the square hole for their purpose. I agree that the business model of the game devs is "wrong" because they were trying to charge one-time fees for lifetime server support. What if there had been no pirates, but paying players had played for 10 months instead? Would that have caused the same server issues? But that is a calculation that seems to work okay-ish with better DRM (or at least it worked great for Diablo 3 in the first weeks - I stopped tracking it after that).
