Reception
iOS 6 attracted controversy because removed YouTube and Google Maps as default apps, requiring them to be manually downloaded from the App Store. Google Maps was replaced by Apple Maps, which was full of mapping and direction at the time of its launch. The criticism led to Tim Cook demanding that Scott Forstall (the Senior VP of iOS software at the time) to sign an open apology letter for the shortcomings of the features. When Forstall reportedly refused to do so, he was fired and Cook signed and released the letter himself.
