Serious question, have you tried to launch and sustain a consumer mobile business in the last 5 years? I have and the paid up front model is very difficult to make work. As much as users say they want to pay once, what they actually want is to pay once and receive a steady stream of features, improvements, updates for new iOS versions etc. The idea that there are no server-side expenses doesn't make a project like this static, iOS itself is a moving target for developers before you factor in user expectations from modern software.
