You know… Linux is not Ubuntu. Can we please stop acting like Ubuntu is the only GNOME-using distro out there, please?
None of these are Ubuntu specific, therefore they cannot really be considered UBUNTU themes, can they?
This is one reason I gladly left for Arch, because at least Arch users can tell the difference between Linux, GNOME, and Ubuntu.
Ofcourse you can apply those themes to other Linux distributions like Linux Mint, Fedora and openSUSE. For your information:
Linux is an open-source version of the UNIX operating system.
Ubuntu is a free Debian-derived computer operating system based on GNU/Linux.
GNOME is a graphical user interface (GUI) and set of computer desktop applications for users of the Linux computer operating system.
