Ubuntu was always the benefits of Debian without the inconvenient restrictions anyways, it wouldn't be surprising if their contradictive philosophy caused them to collapse by inability to eat the cake while having it simultaneously.
I've switched to Debian in professional servers around the time I learned how to use it without a Graphical Desktop Environments, that's roughly the stage at which a growing devleoper should drop the Ubuntu training wheels. Don't carry that into the workplace whenever possible.
