Blame them for not giving ground to their competitors?
I would not however expect a company to do something that would harm them just to please me. They are a business trying to make money to survive. Doesn't matter if it is a massive company or small startup.
EDIT: Ideally I would have like the Google app to have come out a lot quicker than it did so the transition period was better but I'm not sure who to blame for that. Odds are it was Apple who pulled the rug out from beneath Google's feet during the negotiation but that is all here-say and conjecture. Probably 10 years from now we'll read in some book how shit went down.
I've converted dozens of people over to Apple and no one has complained that they should have gone to Android or stayed with Windows.
