Another point is that SFU is an add on to Windows, which is a Microsoft brand. UNIX was
an AT&T brand before it was sold. BSD is not UNIX because the people who developed it
wanted to be released from AT&T licensure. At one time a group of people working for
AT&T Labs went through the "free" BSD code and compared it line for line looking for
AT&T code. They found none, so BSD is not UNIX.
Apple on the other hand had a license to sell an operating system called UNIX.
At one time it was based on the AT&T code and called A/UX. They still have that
license and as long as it is not in the open source portions of the operating
system (which I understand now are none), they can include as much AT&T code as
they like, and call the result UNIX. (even if it contains NO AT&T code).
