The Apple TV+ app is available non-Apple hardware such as the (Android TV based) Nvidia Shield TV just like Google's You Tube TV and Google Play Movies apps are available on Apple TV hardware.
The Apple Music app is also available on non-Apple hardware such as the (Android TV based) Nvidia Shield TV.
So, the playing field is (theoretically) even and nobody is being forced to buy another company's hardware to use their software.
It's hard to imagine Apple can reasonably expect millions of users with Android based hardware will also buy Apple hardware and/or that Apple wouldn't want the Android user base subscription business for Apple TV+ and Apple Music.
The current reality is the Apple TV+ app has had issues on non-Apple hardware and though the Apple Music app is available for Android, it doesn't (yet) support Apple Music Atmos content. But I think the Apple TV+ on Android issues will get ironed out and Apple has stated that
Spatial Audio with Dolby Atmos also coming to Apple Music on Android
Having said that, the pessimist in me can't help suspect that though Apple may deliver on the Apple Music Atmos for Android that will only include phones and not devices such as the (Android TV based) Nvidia Shield TV, kind of like the Amazon Music situation with the Sony 360 audio content only supported on the Echo speaker and phones. But as an Nvidia Shield TV owner I'm willing to wait and see at least for a little while. It will be interesting to see who Apple chooses to exclude (if anyone) from their ultimate target user base.
