The number of people opposing these changes in this thread because "it will make their walled garden experience worse" without being able to bring up a single valid reason why would that be is astonishing.
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. 2. I don't want my phone to run arbitrary code, that's what my Mac is for. People install unknown third-party apps on their iPhones all the time, which is safe enough. Now imagine Apple was forced to make iPhones…
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.
