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?
no, it’s not
I think this is a Ship of Theseus thing here that we’re going to argue about because at what point is it just UNIX-like and not UNIX?
UNIX-like is definitely a descriptor currently used for Linux.
Even the Wikipedia entry starts that way.
It’s Unix if you pay to have it certified (assuming it’s compatible to begin with). That’s basically it.
Some Linux distros have
Some commercial ones did at some point. I’m not sure if they still do.
The question is whether their users care or not I suppose.
Yes, but it’s not Unix. That’s literally part of GNU/Linux’ name.
Mac OS is more Unix than Linux.
