It is based on the MIT/XFree86 license as it was around 1999. The
precise wording is here

Interesting. Is that simply because they are then not restricted to
Apple hardware?

Or does Darwin have some advantags over OSX.

(I have never used Darwin, OSX or any Mac except for a few minutes
about 13 years ago.)

I think the port to Darwin/x86 was chosen as the easiest thing to do
in order to learn how to port poplog, given the complexities of
bootstrapping involved, since most of the poplog core is implemented
in pop11, which requires a running poplog to build a new system.

The people doing the work had never previously used poplog or pop11,
let alone ported it.

For anyone interested there's information about porting
and rebuilding poplog here.
