Where are you figures?
To the author of this article.
You have made a lot of assertions, rehashing "what everybody knows". But can you back it up with real evidence? There are a lot of "news" items all repeating the same assertions, and all referencing each other and a comment by Linus Torvalds. In his time Linus has criticised every desktop, next year it will be KDE again.
How many Gnome Shell users are there in the world? How many Cinnamon, Unity, Xfce4, KDE and Enlightenment? A group of angry and noisy bloggers filling comments sections does not imply "everyone". I could almost guarantee that Unity would win by 20 million users (a rough estimate plucked from the air). Given the popularity of Fedora and Debian then Gnome Shell will be at number two (if not now, soon). Debian Wheezy will be Gnome Shell 3.4 by default (news items to the contrary have proven to be rubbish). Linuxmint might have a hundred thousand users, split over their desktop offerings. Cinnamon and Unity are merely alternate Gnome 3 shells, without Gnome they cease to exist.
I am a happy Debian Sid Gnome Shell user. There are possibly millions of Gnome Shell users, who knows? The difference is that we do not usually fill comments sections with angry comments. We just get on with using our computers. And given some of the rubbish printed above I think many of the commenters have never used Gnome Shell, or only in a trivial sense. I have themes, I can maximise and minimise, alt-tab., task switch. I do not know what Gnome Shell you are railing against but it is not the one I use. Locked down and not configurable? Seriously? https://extensions.gnome.org has 20 pages of extensions and growing. Gnome Shell can be bent and twisted in a myriad of ways using extensions and Gnome Tweak Tool. Gnome Shell leaves Gnome 2 in the dust for modifiability. Gnome 2s configuration superiority is another myth that "everybody knows" and rehashes without thought or research.
