If you used Gnome back in the day you know there was a lot of that configurability built in. Then one day the developer decided to start taking it away. Slowly but surely all the ability to configure Gnome was removed. If you experienced this arc like I did you were left scratching your head.

Yes KDE was always more configurable, but removing what configurability Gnome did have made it less useful. For power users this is a big deal. It is like a company taking away all your features and thinking you are going to like it.
