I suppose you mean the recent news about abandoning Unity and focusing on a gnome shell desktop for 18.04 LTS? Sure, it must suck for those who have invested a lot of their time and soul into Unity and are now losing their jobs.
Personally, having used fvwm, olvwm, afterstep, window maker, gnome 1, 2, 3, kde 1, 2, 3, 4, 5, fluxbox, unity, xmonad and a dozen more or less shorter acquaintances, my experience is that I can get work done on all of them. What the Linux desktop needs is not yet another reiteration of roughly the same concepts, but more elbow grease and polishing. Which happens when you have more users and developers. So with three of the major distros shipping with gnome 3 out of the box (ubuntu, fedora, debian) I think this will eventually be a net positive for the Linux desktop experience.
