That being said, I am also not fond of resourceful studios cloning other successful games.
This doesn't surprise me.
An important distinction.
Anecdotally, the apps with good ratings that I saw in the App Store charts have never been rip-offs.
As far as I can see this is not about protecting gameplay concepts, rather than brands.

I've seen them myself, it's why I apply WhoisGuard to my domains.
But why would anybody make an app called "<popular app> Fan App" if it's not to take advantage of its fame, confuse users and make quick money (with ads or affiliate links or whatever)?
Restore balance to the force!
Zynga does clone games (like nearly every studio does). However, their games are clearly distinct and not intended to trick customers of a competing product.
