Looks like its just another Linux variant, & we have plenty of those. Some use QT, some GTK, others FLTK.
Its the mix & match of Linux based systems that makes them what they are. Then of course there's Ubuntu, origionally a good system that has gone its own way. Everyone seems to think they can do better than the last. Its all about choice, so let them try to find themselves a following.
Personally, a lightweight WM is all that is needed for a GUI system, everything else is bloat, but each to their own.
