I think there's a few layers to this:<p>1) Forstall apparently wants to be CEO, and run the company. That puts him at odds with Cook (the CEO), and Ive (who wants to drive Apple's design decisions).<p>2) He's divisive. There's claims that neither Jonny Ive nor Bob Mansfield would talk to him without Tim Cook mediating. There's also claims that he "managed up" (showed off to the boss) better than he "managed down", and stole credit while deflecting critisism.<p>3) He was the guy in charge of Siri and Maps.<p>4) He was probably the one driving the post-Jobs war with Google.<p>Siri and Maps are Apple's way of fighting Google. Siri competes with Google Search, and Maps competes with Google Maps. There are reasons why Apple wants to spite Google, but the whole strategy could also be Scot Forstall's way of creating his own empire in Apple. Going head to head with Google requires lots of resources, which would all be under Forstall's command.<p>I don't think it's a good gamble for Apple. Google doesn't really hate Apple. I bet they'll port everything they can to iOS, as long as they can keep pushing their ads. Nexus might see Apple as a competitor, but Nexus isn't worth as much as adwords. As Eric Schmidt said in an interview - "It's their call".<p>If Apple goes down the path Forstall wants, they'll be going head to head with Google in the things Google is best at. If they stop trying to turn into a data / AI company, they can focus on what they do best - making easy to use devices which sell like hotcakes, and command a fat profit margin.<p>Android will hurt them, but as long as they focus on their core strengths (hardware, marketing, industrial design, interface design, and integration) they'll continue to do pretty well. They milked the iPod for a decade, despite there being plenty of better value competitors. They can do the same with the iPhone. They can do the same with whatever the next big thing is. I'd say going to war with Google will be at best a waste of time, and most likely a string of humiliating losses.
