a) Android becomes the "write once, run anywhere" platform, attracting developers away from native iOS development.
b) Android loses app exclusivity that pulled/locked users into the platform.
Was that ever a thing? I can think of apps that had this effect for iOS, but did it ever work in the opposite direction? I got Android because it's less expensive...
I wonder if it has anything to do with the fact Samsung, the most successful Android manufacturer, is in South Korea.

Just to give an example, Naver (the dominant South Korean internet company) launched Pholar, which is quite similar to Instagram, in March this year. Pholar is currently only available for Android.
I also like being able to configure my homescreen and having different keyboards (though the latter's shown up in iOS now)
There's some feature differentiation for sure, though iOS has the advantage on some things (I would kill for fingerprint unlock)
