I think many who extol Android's flexibility fall into the tinkerer category, including some tech bloggers. They love all the ways they can customize their phones, not because they're seeking some perfect setup, but because they can swap in a new launcher every week. That's fun for them; but they've made the mistake of not understanding how their motivation differs from the rest of us.
A whopping 70%-80% of the world's smartphone owners have opted for Android over iOS. You could easily argue that 3-4 years ago, when Android was brand new, that it was for early adopters and tinkerers. To still trot out this ridiculous characterisation now that Android is on the vast majority of smartphones sold is borderline insanity.
Choice is not Android's problem. People who assume out of a misplaced arrogance that they represent the average consumer are the problem.
