Ask HN: "What's the Word" and IP protection on the App Store

Apparently, there's a recently popular game called "What's the Word" on the IOS App Store. However, if you search for it, you'll see a bunch of games WITH THE EXACT SAME NAME AND SAME LOOK, to the point where you can't tell which is the actual real game. There's even one purporting to the the "Official" version, when it's not.

How can the App Store allow this brazen theft of IP?

And does this disincentivize developers from releasing anything if they can be so completely copied to the point where they use the same name?
