I didn't mean to be obtuse, but I see that perhaps I was. Let me try this again.
I have never heard of anyone who has chosen KDE over GNOME because Qt is GPLed. However,
there have been whole distributions that have gone with GNOME over KDE because Qt is GPLed.
For instance, I remember the disappointment of hearing that Bruce Perens had chosen GNOME for
UserLinux, way back when. (See http://www.linux.com/articles/33279.) But that hasn't turned
out to matter much. ;)
Whether or not this is sensible behavior, it happens--to KDE's detriment. And again, what I
think doesn't matter one bit. I certainly don't have anything new to say, which is why I only
mentioned the whole issue in passing.
