I’ll admit I’m pretty staggered at the blinkers in this thread.
As much as anything, that 30% pays for OS development.
I’m an Apple user. I’m very happy with the deal I have - buy a phone every couple of years, get free OS updates and security fixes, access to an App Store that “just works” in delivering me free and paid content, etc.
And I really like the fact that every software developer gets the same chance of me downloading their app from the same store.
As others have said, 30% is not huge in mark-up terms. There’s this obsession with the idea that the internet is cheap - it is not, but it is flexible.
Fortnite’s developers don’t like that their successful app should be so encumbered. Of course not - successful companies always like to “pull up the drawbridge” when they’ve made it.
The *next* successful app can just as easily come from a small startup under the current model. Which is yet another reason why I like it.
