I think this may be validation of Microsoft's approach with the .NET platform since one its core conclusions seems to be that Cocoa is too closely coupled to Objective-C to make alternative dynamic languages attractive as they don't "fit together nicely". The other line of discussion it goes down is whether or not Objective-C is the best option, but that's always going to end up being a matter of taste.

I don't think he's passing judgment, saying that Cocoa is too closely coupled, I think he's just comparing why it works better with Objective-C than with Ruby. Amongst other interesting projects are Nu, a Lisp designed for Cocoa and Objective-C; and MacRuby, a fork of Ruby that uses Objective-C's runtime and garbage collector, and language tweaks for named arguments.

He doesn't really present any evidence as to why it works better with ObjC than Ruby, though.
