You are correct in that if I subscribe through Apple, that Apple gets a cut, and if I subscribe via the web they do not get a cut. This makes sense, since Apple is providing a subscription service. I don't have any problem with this model. It's convenient and I've used it in the past.
However, Apple also wants a cut if I were to purchase a movie through the Amazon Video app. Amazon has disallowed such purchases for this reason. Instead, I have to go back to the web, make the purchase, and then I can view it with the app.
Some may argue that this is a fair price for having your app hosted on the app store. However, since Apple prevents any other means of me getting apps on my phone, I find it unfair rent-seeking.
Worse, Apple very clearly wants subscriptions to work just like in-app purchases.
