Amazon Video - subscription outside of the app that lets you play prime movies or you can purchase or rent a movie from Amazon’s website and watch it on the app.
Amazon Kindle - you can buy a book on Amazon’s website and download it to the app.
Coxmixology - again, you can buy a comic on the website and use it on the app.
SlingTV - you buy a subscription on the website and stream video on the app.
DirecTVNow - same as above.
Google Play Video - same as Amazon Video.
Spotify - subscription you buy on the website and stream music on the app.
Should I continue?
Any app makers not happy should boycott the platform and just release Android apps. Of course, they’d also need to avoid the Google Play store as they have pretty similar rates to the App store[0]

On the Android side of things, Google doesn't have near the same level of control, so that is false equivalence. One can easily side load apps, and people do all the time (Fortnite for example, couldn't happen on iOS but did on Android). There's also competing app stores (F-Droid, Amazon App store), so a very different situation. You can also run any OS you want on your device if Google's Android flavor isn't to your liking. Google also doesn't make/sell most of the hardware.
Microsoft got in trouble for simply making it very easy for people to use IE instead of Netscape and Word instead of WordPerfect. Imagine if they had gone a step further and mandated that only apps that pass a Microsoft review process could even be installed at all?
iOS does not because there are more Android devices than iOS devices.
Regarding your first part about apple having a monopoly on what runs on an iPhone: so does Samsung on fridges/washing machines/ovens, or almost any other embedded system for that matter. My router-maker also does not allow me to put different software on my router, and I can’t run software that hasn’t been allowed explicitly by Microsoft/Sony on an Xbox/Playstation.
This is ‘whataboutism’ but why is it only an issue for Apple devices but A-OK and ‘normal’ for every other example?
technically it’s called “in-app purchase” [1]
