It was directly stated on NASA TV that Solaris is the only OS that NASA uses for manned space flight because "it absolutely must run", and Sony uses BSD as the OS for the Playstation 3/4 for the same reason (stability under extreme use).

Well, to be a true Unix, in theory, it has to be certified. OSX is
certified as Unix, FreeBSD isn't. There was a book out years ago, Unix
administration, where they covered, if I remember correctly, AIX, HP-UX,
Solaris, now owned by Oracle, RedHat and FreeBSD.

Some of the BSD folks get really into the whole, It's Unix, Linux
isn't--actually Gnu is a recursive acronym, for Gnu is Not Unix. These
days, Linux gets further and further from the Unix idea of have something
do one thing and do it well.

The answer is that most things run on the BSDs, but not all, and they
frequently have to be somewhat re-written.
