No, what Apple is doing is asking for 30% on your electricity bill from your power company, because you downloaded an app on Apple store. basically if you sign up using an app, apple wants 30% of what-ever for providing nothing else than the initial download. And you can't add a signup here in your app.
I believe it is actually 15% now for subscriptions but your description is valid.
However, the thing that most people overlook is the fact that this isn't much different than how Apple makes it money on other apps.
If you buy an app that costs $4.99 as a one time cost, Apple takes their 30% cut and the developer gets the rest.
Spotify isn't a one-time cost app however. You are able to download the Spotify app for free (which doesn't give Apple any money) and then you have to start a subscription to use it.
You can either use a subscription that you've already set up via Spotify's website (which also doesn't give Apple any money) or you can initiate a subscription through the app itself, which uses
Apple's App Store subscription features.
It is when using
Apple's App Store subscription features that
Apple take a cut of the profit. In the case of subscriptions it is a 15% cut. As long as you continue to use
Apple's App Store subscription feature,
Apple will continue to get a 15% cut.
Essentially, Spotify is requesting that they be able to use
Apple's App Store subscription features for free, while no other developer is allowed to do so.
I also find it ironic that Spotify states on
their own website that "
Apple forces us to apply an additional charge on subscriptions made through iTunes and its App Store. The good news is you don’t have to pay extra: Paying for Spotify through Spotify.com instead means
you’re cutting out the pricey middleman and coming directly to us."
In reality, Apple isn't forcing Spotify to do anything. Apple is requiring compensation for the use of a service that Apple provides, which is the same requirement it puts on all other developers. Spotify is choosing to raise the price of their subscription service initiated through Apple's App Store subscription features to offset that 15% cut that Apple is taking from their profits.
Spotify's recommendation has nothing to do with "cutting out the pricey middleman" and is not designed to help the consumer. They just want 100% of the profits for their service 100% of the time regardless of the method of distribution.
Sorry, Spotify. It doesn't work like that. Go have your tantrum somewhere else.
