First of all, I doubt that the average smartphone purchaser is voting on this issue with their dollar anyway (though I realize this is sort of ducking the whole argument in a wussy way!).
I think there will always be a market for more than one phone platform, just as in computing. I'm mainly disputing the gp's assertion that people are rejecting iOS devices because of the curated OS. For instance, iPad sales are killing all the other tablets -- is that despite the average person's supposed hatred of the closed environment? Are you willing to make that argument?
