Yet most of the world runs Android. Its main value proposition was always wide selection of hardware for however much money you're willing to spend, not its relative openness.
I make relatively decent money by our standards, and I wouldn't even think about dropping $700-1000 on a phone (which isn't even officially sold or supported over here). For the vast majority of people it's their whole income over 2-4 months. I don't know or care how much you make, let's say it's $10k per month. Imagine if you had to pay $20-40k for a phone which is good for maybe 5-8 years.
And most of the world is like that.
A locked-down Android is pointless.
