You are trying to tell me that credit card processing fees are negligible, software engineers work for free, advertising doesn’t require overhead, etc…
I guess that kind of thinking that everything is basically free is why alot of startups just fail so easily.
Your profit is whatever your revenue minus costs. Plenty of app stores have operated in the red that we know this isn’t trivial to get right. It definitely is nowhere near negligible as patent asserted. I’m frustrated by how dumb HN is getting lately.
It doesn't cost that much to maintain and run the appstore, it is almost all profits.
