That's a moot point. You cannot count that, and any stats from Redhat which supports just Gnome will not prove anything.
Any online pools show that both KDE and Gnome have big usershare. Furthermore both Qt and GTK+ are part of LSB.
I'm sorry but with the current mind set, KDE people will need to hack on Xserver or write their own Xserver soon, because it may become to tied to Gnome. I'm exaggerating sure, but it shows the current situation. Yet again you see KDE users complaining in gnome topic, you do not see the other way around so that has to mean something, or do you really think that all the trolls live just on the K front ? It just means KDE users have some good reasons to complain that's all.
