If Raffael had said that OS X is a "BSD-licensed Unix", your argument
would be on point (and Raffael's would be very, very silly). However,
he said nothing of the sort.

Whether it's a BSD Unix or not has nothing to do with its licensing,
and never has. The BSD Unix codebase was intentionally licensed in
such a way as to allow people to make and sell partially or wholly
closed-source, commercial derivatives. Over the years, a lot of
vendors have taken advantage of this opportunity, including Sun, NeXT,
Apple and, IIRC, Digital.
