Was it somehow unclear? Gnu is Not Unix.
Come on, man. GNU was designed as a drop-in replacement for Unix and you know it. The acronym refers to the license and the GPL not the design philosophy.
From the GNU manifesto:
"Unix is not my ideal system, but it is not too bad. The essential features of Unix seem to be good ones, and I think I can fill in what Unix lacks without spoiling them. And a system compatible with Unix would be convenient for many other people to adopt."
