Gut reaction: I feel like Android would not survive Google being forced to remove all their apps from the Google play store.
Android is perhaps the closest in comparison to Microsoft/Internet Explorer. Spin off Android into its own company, including the Play Store. There would be nothing stopping Google from keeping their apps in the Play Store, but they would sit on the same level as competing mapping and search apps, and users would choose which one to use instead of have it preinstalled.
I actually think Android is a really bad example precisely because all the useful google apps ARE separate from the OS. Its just that what people think of as android is actually mostly Play Services now.
