Fair point, but I see it more as a question of degree. It's not preposterous to say "I'm leaving you because you do too much of something I don't want (pollute, overcharge, play bad hold music, whatever) for someone else that does a little less of that same thing that I don't want (pollute, overcharge, play bad hold music, whatever)" If the market pressure is strong enough (I don't think it is, this is all hypothetical) then it could be something that Apple and Microsoft and Android and others actively compete on.
