If you don't develop for Apple because you are under the misapprehension that the Play Store is more open there will be plenty of people willing to take the money.
The Play Store does allow app launchers (alternative home screens and themes are even popular), but they do still ban other non-malicious apps, most notably: pornography, apps that block ads in other apps, and YouTube video downloaders. Though the latter is allowed in the Amazon Appstore, I think.
