No one forced developers to write apps for it
The market, Apple's market share does. You're hardly going to have a viable/competitive dating app or music streaming service without offering apps for Apple's platforms.
It's not good for society when they are given ways to interoperate with that operating system via IP theft
There's no theft. Just careful, limited regulation.
Because then those actually doing the work do not have incentive to create new features.
I remain confident that they will - cause they earn good money from doing so (such as by differentiating their hardware products with such features).
Uber and DoorDash provide physical goods and services which are not enjoyed on the device they are ordered on.
Exactly. They don't depend on the platform nearly as much.
That's why Apple exempts them and provides their service and app store to them for free:
To create an ecosystem and monopoly that others can't ignore (among them developers / providers of paid digital goods/services).
I subscribe to Microsoft 365 through iOS and Apple gets 15%, not the 30% the App Store debuted with.
Why? When you subscribe, Apple gets 30%.
When you merely retain that subscription, then it gets down.
Point taken - but doesn't change the larger argument.
It's just an incentive for Apple to earn recurring subscription commissions.
I love how it never occurs to those citing this that the reason Apple controls half of consumers spending on mobile apps is that customer's prefer Apple's approach and are justly rewarding them for their approach.
It absolutely occurred to me.
There's merit in a centralised application store run and governed by the OS developer.
There's no consumer benefit in them charging supracompetitive commissions though.
