Predictably, this is where the goalposts have moved[1] but it's really orthogonal to whether there's value or not. Also as pointed out elsewhere, Steam is in a competitive market and charges the same commission. Also in Apple's favor is the well attested to value of the App Store vs Google Play and others in terms of raw revenue.
[1] 'Predictably' as in "Being locked down or not is a red herring to the value argument" in grandparent
That’s the value add IMO, not the aluminum case, the Apple logo, or anything else. A locked garden isn’t perfect, but it’s better than an open sewer.
The Apple App Store does not fill all those conditions. In fact, I can safely say it does not do some of things you say, including the part about stuff just working.
