Why? A small developer could use something like Stripe or Paypal to collect payments, and enjoy fees significantly lower than 30%. They wont even need to roll their own auth system, as they could use sign in with Apple. What i dont understand is how this checkout process will look. As I understood it, devs would only be allowed to “steer” users to other payment options. Does this mean they cant include a non-Apple payment SDK in their app? So they’ll need to open a modal browser window to complete the checkout process? If devs cant ship a payments SDK, they’ll be at a disadvantage with Apple Pay, because the checkout experience will always be slightly worse. Maybe most users won’t care?
