Perhaps you meant OpenSUSE MATE.
Arch Linux has used rolling updates for a long time (my friend has been using it for ~10 years now).
The same general idea applies to most distro variants; "we can make a better distro than this."
I get the impression that many users left Ubuntu because of Unity and GNOME3.
I know I did (I switched to Linux Mint).
KDE have also apparently decided to copy MS' modus operandi regarding features.
When the developers noticed that most users were disabling Disc Indexing, they used the MS W8 Start Screen solution; they removed the disable option.
