Agreed for sure! But it does look like additional FreeBSD stuff was added as nextstep turned into darwin/osx.
I found a couple of other articles, I didn't know Linus turned down the job offer from Steve Jobs before they hired that famous FreeBSD developer. It's funny to think how things might have turned out in an alternate reality :) http://www.wired.com/2013/08/jordan-hubbard/
It's also fascinating to try old versions of nextstep and rhapsody in virtual machines, you can really tell how osx traces straight back. Even the installer is so similar still, comparing nextstep 3 and yosemite (if you bring up the console window during its progress)
