A simple anecdotal example. Last week I subscribed to HBO Max.
[
<SNIP>
… the App asked me to subscribe, a pop up appeared and pling … 30% to the cashier. All for me to be able to install the App and use the service on my phone and other devices of mine!
Which is what any store does - markup teh price for their profit. That's what Apple does - developer sets a price and they add their 30%.
Now I could have went to the website and subscribe from there, but has I was already on HBO Max (the App) ... what would be the point of leaving it, put an URL on the browser, sign in again so on and so forth?
As a customer I don’t see at which point the service, the App Store, made an effort to sell me the service if not for the fact that it is the only way to install Apps on my device. Even the App itself made a better effort by asking me for payment at the right time. Don’t see much of a Marketplace on this workflow do you?
Apple enabled ou to do everything within the app; and when you do that they get their cut. Is HBO Max cheaper on the website? If not, Apple's cut is irrelevant to the consumer because they pay no penalty for using the store.
One benefit is developers know when they roll out a new feature or fix bugs, the users gets notified and often they just get automatically updated.
On top it needs to compete with Apple TV+ which basically is free of the 30% cut I guess.
It all depends on how they allocate costs and revenue.
This is the thing of vertical integration of totally disparate businesses. It’s really powerful to the point of passive income.
This is what happens most of the time in my case. Not to say that there aren’t cases were the App Store generates the lead, mostly games. but even than … well you have Apple Arcade undercut. Certain business and services might take advantage of the typical marketplace browsing workflow this will never leave the App Store even if given the option.
Not to say that what you mentioned aren’t interesting benefits for businesses in general … but a benefit is only a benefit when optional. Otherwise is waste of resources.
This is one situation were regulation kicks in.
To me, the question is "What value is there in being able to reach Apple' user base for essentially no cost until you sell your app or subscription?" I suspect a 30% cut is not an unreasonable answer; given what the historic return was to developers before app stores.
Businesses will have to decide if the Apple App Store is worth it once their are alternate stores. Apple will have to decide how to generate revenue from apps to make up for any lost revenue. I suspect, given Apple's App Store user base, developers will stick with it in most cases or face a significant loss in revenue. I also doubt alternative stores will be cheaper in the long run, and may be more trouble than they are worth.
Some developers, if sideloading becomes available, may leave the App Store. I suspect leaving would cost them more than they would gain from getting a smaller cut from an alternative or being solely on their own website.
At any rate, by the time the law actually goes into effect, who knows what Apple will do? Apple has a lot of options, from unbundling fees to building in security features that allow users to know when a 3rd party app is accessing an API and asking the user to allow it, much like they do with tracking currently.
It would be interesting if Apple decided to end all user tracking if tehy felt the benefits to them are less than the PR of being a non-tracking phone. Developers would have to find alternate ways to track, and I doubt the argument "Apple is unfair they won't let us track users" would fly if Apple did no tracking whatsoever. I doubt it, because there is some value to it, such as weather apps, calendars, etc. but they could cut out a lot o specific data to make it harder to build user profiles.
Apple could build encryption into the hardware so while a third party software program could access it, it would only work with phones that choose to license the chip. They could go completely open, but that's not their style.
