..Because Unity, and now GNOME, are so radically different from the traditional Windows interface, some people flocked to Linux Mint and its familiar Cinnamon desktop environment. Mate and Xfce are Mint desktop options too, but make no mistake, Cinnamon is the crown jewel of the distro. Sure, there are other nice aspects of Linux Mint, but ultimately, it is familiarity with former Windows users that make the OS attractive to many.
Unfortunately for the Linux Mint developers, their operating system has essentially become obsolete. You see, as of today, Ubuntu Cinnamon has become an official Ubuntu flavor. Why should anyone use the Ubuntu-based Linux Mint with Cinnamon when they can just use the now-official Ubuntu Cinnamon instead? The efforts of the Linux Mint developers are simply unnecessary at this point…..
