KSOS and related work was sponsored by several DoD activities, at least the
part that I worked on - after 1983.
We've wandered a bit afar for TUHS(?), but, the PWB and other software
wasn't pirated, it was supplied as "government furnished equipment" as
part
of each contract.
PWB and other software we got via the NSA's Tycho site, etc. NRL (and then
others) funded later KSOS work, including the Advanced Command and Control
Testbed (ACCAT) and various multi-level secure "Guard" systems, for the
Navy, Air Force, USAFE, etc.
All of which ran on PDP-11s, using the KSOS kernel and userspace, almost
all built by using PWB as the build platform.

I don't think it was pirated. I'm think it
was a special license Ford Aero
got due to the work with the USG. I sort of remember KSOS and if I'm
correct that was a DoD funded effort for the Orange Book. So it would make
absolute sense that Ford Aero might have used the USG connections to
convince AT&T to release it to them. As I said, Al was very skittish about
anything that might be misinterpreted by the Justice dept. But if DoD was
asking for it, Al could show the Jusitce -- "hey -- your people asked for
it -- we were not selling it."
