Why would devs lose the ability to host free apps?
what pays for the app store infrastructure? the fees apple collects from the sales of products on their hosting platform. if those fees dry up, so does the platform.
Help me with this: Big companies would use cheap payment providers, but these providers would be simultaneously too expensive for small devs? Huh?
if netflix started accepting in-app payment, but used a 3rd party, the number of transactions per-month would ensure they got a very favorable rate, where-as Jim's Video Streaming App would not be able to guarantee those transactions, so would be stuck paying a 3rd party a high rate.
