On top of this, when Apple releases new frameworks, the Obj-C users get to use them immediately. People using weird bridges are giving their competition a huge time boost by voluntarily delaying their own access to the new stuff.

I worked for a company doing Mac apps in REALbasic for several years, and this was a constant hassle. Additionally, RB chose the wrong backend for their compiler (Carbon instead of Cocoa) and there were multiple years of setbacks due to Apple hemming and hawing about whether they were going to deprecate Carbon altogether and RB porting their entire framework to Cocoa. During that process, everybody who emigrated to Objective-C got their stuff to market sooner, and with access to newer libraries to boot.
