Who is attacking the AppStore? Who is afraid Objective-C and Xcode will be the next development platform? What does "the next development platform" even mean?

Who is attacking the AppStore? Who is afraid Objective-C and Xcode will be the next development platform? What does "the next development platform" even mean? ObjC and Xcode are just fine, and developing apps for the iPhone is a lot of fun (outside of the AppStore experience, apparently), but I'm not sure they deserve any sort of conspiracy theory.
