I think the best thing would be if Apple just allowed other payment providers so like Stripe and I'm not sure I haven't followed it totally if they now kind of have been forced to do that but I think then you have a free market where developers can choose whether they want to use apples in app payments which are easier and probably results in better conversion rates or they want to use an external like Stripe or something like that. I don't think it's reasonable to pay for the app hosting or development other than the $100 fee per year that should certainly cover the cost of storing a few megabytes of an app.
