This was a good (if depressing) read, and reflects exactly my feelings about how and why GNOME has failed, and the absolutely unforgivable travesty which is the deliberate breaking of GTK+.
When such issues, clearly spelled out, still don't seem to have made it into the collective GNOME consciousness, it does not bode well for the future of GTK+. There was (and is) a massive userbase of GTK+ application developers who use GTK+ outside of the confines of GNOME. Are they all going to be completely screwed over by these people? It would unfortunately appear that this is exactly what is happening.
The main problem seems to be the unhealthy obsession with the "brand" and superficial appearance of the software to the detriment of all else. There are much bigger fish to fry than this superficial frippery.
