8. Apple wants to leverage revenue opportunities

Taking into account mobile advertising, Apple surely wants to make some cash itself. Thanks to its iAd platform, Apple could integrate ads into its Maps application and any program it might use to replace YouTube. Apple’s revenue opportunities might even extend beyond advertising to other options, like virtual goods or company lists in Maps.

9. Apple wants to control

Apple is known for its control in the market. The company hates allowing other companies to impact the overall usability of its operating systems. As a result, Apple might have finally decided that all native applications running in iOS 6 should come from its own developers. If owners want anything else, they’ll have to go to the App Store to find it. This might just be another one of those decisions which revolve around Apple’s penchant for control.

10. Doing this with iOS 5 would have been a bad idea

If Apple would have ditched two popular mobile applications in iOS 5 and launched the barely updated iPhone 4S at the same time, critics would have hit it hard. But now that Apple is expected to launch a major iPhone hardware update this fall, the lack of a few popular competing apps might be overlooked.
