Unix is basically a brand name.
BSD had to be completely re-written to remove all Unix code, so it could be published under a free license.
It isn’t Unix certified.
So it is Unix-derived, but not currently a Unix system (which is a completely meaningless term anyway).
To make it more specific I guess, what’s the problem with that? It’s like having a “people living on boats” and “people with no long term address”. You could include the former in the latter, but then you are just conveying less information.
I’m confused on why they separate BSD from Unix. BSD is a Unix variant.

So is Linux. So I guess the light blue is all other UNIX variants?
