What he fails to account for is that this is the "Music" app, not the "Apple Music" app. More than 90% of iOS users don't subscribe to AM, so the app has to accommodate everyone that wants to play just the music on their phone through this app.
I fault Apple for this (but this guy still fails to account for it)... Apple hijacked the Music app for AM when AM should have been a separate app. Either that, or disabling AM in the settings should truly give you back the Music app navigation and functionality, pre-AM.
I can't be alone in not wanting stream my media or show my entire cloud music library on my phone. I chose the music I wanted to sync because that's the music I wanted to listen to, and I don't want to have to wade through all the streaming/curation/recommendation cruft to do that.
