They just got fined 500 millions for failure to comply so I'm not sure adept is the adjective I would use.
So the question is: Would more convincing compliance have cost Apple more than single digit percentage decreases in Appstore sales? Comparing the F-Droid vs Playstore situation, this seems unlikely to me.
Whether Apple can be cheaper isn't really the point (they should be, digital services are a very high margin business). It's that they're anti-competitive to the point that the market for paid apps and in-app payments became inefficient (in a financial sense).
It doesn't cost that much to maintain and run the appstore, it is almost all profits.
I guess that kind of thinking that everything is basically free is why alot of startups just fail so easily.
Sure, a half a billion fine sounds like a lot, but if you don't have another number to compare against, you can't tell if it was clever or not.
Ie. "More than half of users have installed at least one app from a non-apple affiliated store by Jan 2026 or you shall pay a fine of $10 per month per iPhone in use in the EU".
If you ever tried out third party app stores on Android you’ll see what I mean. See also the crappy launchers/stores major game publishers try to force on you on PCs.
