Give me a break. It doesn’t take 15-30% to implement a secure payment system. This is proven by Apple itself: Apple Pay charges very little for secure payments for physical goods.
Also Apple doesn't just support the secure payment system, they also handle distributing the money and providing customer support to the end user and the developer. That isn't free either.
If you don't like the Apple model, there are alternatives.
Apple's argument (which seems compelling if we judge it on the result) is that their model is the best solution for customers and developers.
What alternatives? Without allowing developers to create 3rd-party payment systems, all payments must be routed through Apple.
>Apple's argument (which seems compelling if we judge it on the result) is that their model is the best solution for customers and developers.
Apple's model does not seem to be compelling for developers/content creators. Developers need to pay a large (for some) amount of money and give Apple a large cut of their profits.
It's also unclear why Apple's model is best for consumers. While it seems good because it protects consumers from scams on third party sites, for reputable companies like Spotify or Netflix, there doesn't seem to be a risk, except for increased prices to the end user because companies need to compensate for losing a third of their earnings.
