Apple itself also uses a lot of OSS in the depth of Mac OS X. Just the

Even the browser uses OSS: WebKit.
Indeed so, including much of the OS X kernel, which predates the founding
of Apple Inc (formerly Apple Computer Inc) by several years.
Just invoke, say, on a Hackintosh, OS X using the -v (verbose) boot
option, and you will immediately see the BSD (Berkeley Standard
Distribution) copyright, "Copyright by The Regents of The University of
California", and an exhaustive list of copyright years, many of which
pre-date the founding of Apple itself.
Well according to the canonical listing of the Unix Family Tree,
(<http://www.levenez.com/unix/>) BSD1 dates to 1978; so Apple Predates BSD,
although AT&T Unix predates Apple by several years.
Also Apple is one of the few companies to have produced version on both sides
of the Great Schism; between System V and BSD. OS X is based on the BSD line
(why the Califoria Board Of Regents copyrights are there) but A/UX, Apples
FIRST Unix, was a System V-based system.
The opnly other one I'm familiar with is HP's HPUX, which was a frankenunix cobbled
together from the corpses of HP's original workstation versions (based on System V)
and Apollo's (based on BSD) when HP swallowed them up. <shudder> Burn it. Burn
it with fire! Commands were an unpredicatble mix of BSD and SysV syntax.
And, believe it or not, there was a time (mid-90's) when Apple was
actually developing their own flavor of linux, called MKLinux.
