The value of the App store as a safe place to download apps is the hallmark of Apple, and I personally wouldn't trust anyone else with downloads. All some of us are saying is that Apple music has an unfair advantage in not having that extra 30% cost every one else has in monthly subscriptions. It's excessive and puts apple at an unfair advantage, especially since they have a marketplace monopoly.
There is no unfair disadvantage here at all. First, the Apple Music team and the Spotify Music team both developed similar solutions, and they both have to negotiate with record companies and independent musicians about the fees to run their solution. They have the same cost. Independent of that, the App Store team reviews software, publishes it on the store, and collects fees for that. The Spotify Music team pays money for that. What about the Apple Music team? Either they pay the same money to the App Store team, or the App Store Team doesn't make money from the Apple Music team. So the Apple Music team can only be more profitable if Apple gives up money elsewhere.
This is like complaining that Samsung would have an unfair advantage in the phone market because they use their own parts, and while Apple would pay cost + profit for some Samsung component, Samsung would only pay the cost. And that is just as wrong. Samsung's phone manufacturing pays the same price for Samsung components as Apple does, because Samsung's components manufacturing wants to make as much profits as they can to get their bonuses. Of course Samsung _could_ charge itself less for components, but that would increase the profit in one area while reducing the profit in another area.
The real problem that Spotify has is that the AppStore has exactly one set of rules for payments, and applies these rules to everyone, and Spotify's business doesn't work well with these rules. As a counterexample, Dell could write an app that allows you to order Dell computers and components and services etc. from your iPhone and iPad, and because of the exact same set of rules, Dell wouldn't need to pay anything to Apple. Amazon could write an app for a music subscription service that sends a CD of your choice to your home once a month, and Amazon wouldn't have to pay a penny to Apple.
It's not that easy. Since the app store is the only way with ios it would violate antitrust.
That is of course absolutely false. Spotify is selling lots and lots of subscriptions, including subscriptions for Mac, iPhone and iPad users, without using an iPhone app to subscribe. You can go to Spotify's website, subscribe to their service, download a free app on the App Store and listen to Spotify music 24/7 without one penny of the subscription money going to Apple.
Would you even say it's appropriate to use the word "monopoly"? I always looked at it as a walled garden, closed ecosystem.
That's a strange thing in language, that a combination of words can mean something totally different from the individual words. It is a "natural monopoly", just like your Auntie Sally has a "natural monopoly" on Auntie Sally's Strawberry Jam. A "natural monopoly" is not a monopoly. Like a "design patent" is not a patent, "linear algebra" isn't about algebra, and so on.
