Yup, while the Apple fans can believe that it was because Google refused to update Maps, I will, until presented evidence otherwise, that Apple refused to let Google update Maps because they've been working on their own version to roll out.  Plus Jobs hated Google towards the end and this is part (IMO) of the thermonuclear war he declared.
Given how Google operates, I don't believe they just told Apple to go suck it and be happy with Maps as they were.  If they could have upgraded it, I fully expect that they would have.  Android has other competitive advantages, they didn't need to hold Maps ransom.
		
		
	 
You are completely wrong and I have already gone over this earlier in the thread. First, the original Maps app bundled on iOS was created by Apple, not Google. Apple licensed the map data from Google, but it was NOT a Google app as you assume. So it's your contention here that Apple itself refused to upgrade their own map app with turn by turn, voice and vector tiles for five years while Android enjoyed a clear competitive advantage in that arena? I already posted the official 
Google Maps Developer TOS that explicitly denies licensees turn-by-turn, you must have missed it last time. Here it is again:
