> I think the Spotify example is a good one; if Apple kicked off Spotify, there could be millions of people switching to Android just because of that.
We'll never know unless/until it happens, but I think you are 100% wrong on this point—most would just switch to Apple Music. Phones are much too expensive to switch immediately, and while some users might initially want to switch at their next upgrade cycle, they would need to sign up for Apple Music in the interim, and then they'll become accustomed to it.
iPhone users are a captive market. The costs of switching are too high, both economically and in terms of inertia.
