What does it matter if software has marginal costs or not?
The principle is the same, it's a product being sold by a 3rd party which Apple has no involvement at all in its production costs being distributed by the App Store which Apple takes a fee of 30% off.
The costs of software services are part of the cost of a subscription, as the cost of production of something Amazon is selling is part of its cost. Streaming services have ongoing costs for development, maintenance, etc. that physical goods don't have after they're sold. You are just paying one upfront and the other one is ongoing.
> 80% of all Apple revenue from the App Store comes from pay to win games (came out in the Epic trial)
And what's the argument here? That those are easier to produce they deserve to get taken a 30% cut because marginal costs are near zero?
Netflix and other streaming services have much higher costs than these P2W games if that's your argument; costs for licencing content, maintaining infrastructure, paying for development. Nothing of that is cheap, what is the big difference between a product such as a streaming service and physical goods sold by Amazon that makes you not support Apple taking 30% from Amazon per purchase?
Do you think it'd be fair if every Netflix subscriber using Android devices had to share a slice of the 30% Apple takes if Netflix allowed subscriptions through their iOS app and Apple took a cut? Because it's either that or Netflix having different subscription prices between iOS and Android, both are bad for Netflix and good for Apple. All while Apple also produces a competitor.
In what world is this a fair market practice when you have so much power over a platform? And even directly competes with some companies that you are putting in a natural disadvantage?
