As far as I know, right now Google's revenue is coming from ads and not from Android. Exclusivity of apps could potentially help the Android market grow over time. But is Google directly benefiting from this? I think that a larger Android market is just reducing the risks of Google tools/revenue generating apps/services being kicked out of environments that Google doesn't "control". Next question would be: would users of these other platform allow this to happen? As a side comment, I don't think app exclusivity as user acquisition technique is working anymore. It's an important aspect, but it's part of a larger picture.
