As for your second point, fair, but at least then we could blame them for being money hungry.
If you want users to see the app you also have to use the iOS system on iPhone. You have to rely on Apple to build GPUs to process your game effectively. Why is the App Store treated so specially?
If you want to charge people to use your platform there are other methods, e.g. developer licenses.
Your initial comment doesn't change my point, just moves the goal post. If I want to deliver no IPhones, I'm stuck with the system. And you can make the same argument for the Play Store.
I don't think PC/XBox quite fit in the same ball-park. The engagement model is very different on those compared to mobile devices. Which is why video games still cost 60$ but most people won't pay more than a couple of dollars for an app.
I don't think that's the real disagreement we're having though. I think the misalignment is on whether 30% fees are acceptable or not.
And Apple doesn’t “deserve” anything anymore than any company deserve anything. Apple built the iOS and iPhone platform, so they can charge based on that.
> ...lower cuts could result in lower prices
I’m not confident that if Apple stopped taking a cut that companies would lower prices.
