GNUStep makes your rant pretty worthless.  The are outstanding issues 
	PyObjC doesn't support GNUStep yet (needs a volunteer or some of 
Ronald's time)
	Cocoa nib files are not directly portable to GNUStep (and vice versa, 
I guess, I think there's go-between tools though)		- Renaissance which 
lets you do interfaces in XML and works on both GNUStep and Cocoa (I 
have used it, it works), but you can't use Apple's nice tool
	GNUStep isn't so hot on win32 yet

Honestly, I don't care if it's a closed source single platform 
framework.  What I care about is getting stuff done as elegantly and 
effortlessly as possible on the platform of my choice.  Kludge sucks.  
But in any case, there's GNUStep, so in theory in the near future (as 
near as we, the open source community, make it) all this stuff would 
work on Linux and (with some work on the win32 port of GNUStep) win32.

As far as your 'F' goes for .NET, that's unfair too -- there's Mono, 
and the Rotor project (Microsoft's Shared Source .NET implementation, I 
don't believe it has the GUI stuff though).  Mono works on linux/x86 
and can probably be hacked to work on OS X/ppc, though they don't 
officially support it (yet).  Rotor works on FreeBSD, win32, OS X and 
can probably be hacked to work on Linux.
