Because using Android is always extra friction in my life. I have tolerated it because of the ideals of Pixel and Android (which Google has slowly and deliberately evaporated).

Also Apple does a better job at standing up to government bullshit (where Google tends to stay suspiciously silent). So when they are on equal ideological footing, Apple as a consumer product company wins against the Google surveillance apparatus.

Basically: Apple is a better Apple if Google wants to turn itself into even more of a pathetic Apple wannabe.
