because with KDE 4 they change the fundamental design philosophy of the project. I didn't want easy of use, I wanted control, which I why I originally left GNOME for KDE before that.
Now with GNOME making the same design choices, I'm left with MATE, which is just a fork of the the GNOME I want to use, but it's still lacking right now.
I understand that they want the interface to be easy for anyone to approach, but what about those of us who want to do more than just browse the web and share pictures of the grandkids?
I'm loosing all the features of the Linux Desktop that I left Windows for in the first place. *sigh
