> 1. Allowing other app stores would immediately mean each app wanting you to go to a separate store. I barely use apps in the first place but would imagine this being bothersome for those who use them a lot.

Except Android allows other stores since forever and that didn't happen so this is proven to be an incorrect assumption.

I see this and other blatantly wrong, easily verifiable, takes so often that I wonder if those who write even know how things work in Android or they just live in an iOS bubble and assume things about Android.
