Wasn't part of one of the big lawsuits 30 years ago that Microsoft could not market a UNIX derivative?

Interesting question. I remember M/S sold or spun off Xenix, but I thought that was due to them wanting to focus on DOS and Windows.

Found this and the answer is "no" :) Seems they rid of it due to Bell Labs breakup, see "Transfer of ownership to SCO":

  • Yeah, it was before the bigger antitrust suits but IIRC it was part of what set the stage for them

How is Linux a Unix derivative apart from some guy in Finland reading a sysV syscall manual in 1990?

  • I don't think SCO's claim ever got adjudicated but it was enough to let them shake down multiple companies

I mean Microsoft actually had a quite successful UNIX derivative named Xenix in the 80s (later sold to SCO).
