And android does have alternative stores. Amazon, F-Droid and even directly side-loading applications. Not everyone takes advantage and most sales go through the Google Play Store, but it still happens. Apple offers none of that.

AFAIK, Google also doesn't charge for dev-tools or access to dev options. I admit, however, it's been several years since I've done any app development for either, and then it was mostly a wrapper around a browser control with some custom integration for use with NFC.
