I was pretty clear why I included Google. Because using their app store is the single best chance for a dev to monetize their app on Android, or at least to get it noticed. Sure, they can use another store like F-Droid but while the possibility is there, they'd severely limit the audience. And most people are discouraged (for good reasons) from installing APKs from random places on the internet.
Few Android apps are distributed exclusively outside of the Play Store and even fewer get any traction with users, not to speak of being a financial success for the dev.
