Dear Google, Please Force Developers To Follow Android Design Guidelines

That isn't always an option - there are no real alternatives to the official Facebook app, or the official Spotify app, and so on and so forth. It tends to be these really big apps that commit the sin of cloning their iOS interface on Android.

Also how does the author presume Google forces developers to make apps the way the author wants them to make apps? As far as I know, the biggest draw of Android over iOS or Windows Phone is that the market is only curated at the very most basic level necessary to keep it functioning. Is there an approval process for Google Play apps before hitting the market? I don't think there is; if I'm wrong, I'm only slightly wrong.

iOS and Windows Phone are popular among their respective users because of how well-integrated and tightly controlled the experience is. Android is popular among its users in no small part because of how unrestrictive the system is: you can do just about anything. Asking Google to force a design paradigm would just push Android into competing in the same market as the iPhone. It would alienate its fans and destroy the biggest reason Android is so popular.
