    In the 00's, the CS program at my undergrad university had computer clusters with all of the above +Linux +MINIX -Apple -DEC. It was de rigueur then to write portable C/C++ code and (non-GNU) Makefiles.

    Also, lest not forget the contentious one: SCO - SCO -> Sun -> Oracle

    Given acquisitions, the current IP ownership is more like:

    IBM - AIX

    HPE - ULTRIX, Tru64/OSF1/DIGITAL UNIX, HP-UX, IRIX

    Apple - A/UX, macOS

    Oracle - SunOS, Solaris

      If HP and Sun had merged, I wonder if HP-UX would become HP-SUX.

        It’s in the Jargon file. Your comment made me remember this bit:

        Hackers at HP/Apollo (the former Apollo Computers which was swallowed by HP in 1989) have been heard to complain that Mr. Packard should have pushed to have his name first, if for no other reason than the greater eloquence of the resulting acronym.
