Is Google Play like the Apple app store where Apple takes a smaller cut for apps with fewer users?

If so, there's obvious financial incentive for Google to push more people to a smaller number of apps.

In a way yes, though it's revenue based (if you make less than $1M/year) rather user based. I don't think it has much of a financial impact though as, from what I remember, the long tail of apps doesn't make them very much money in comparison to the whales.
