I'm not so sure. I think it'd largely have to do with developers' and consumers' reactions. If Android was suddenly ground zero for innovative, high quality apps, due to Apple alienating developers, I don't think Google would choose the same model. Indeed, you can see Google attempting to attract developers to its ecosystem and away from Apple's in some of their recent developer policy changes (no app review times, etc). But now we're getting way off topic. :)
