Hopefully, I'm not confused about what people mean by NT since I have to
understand it fairly well to do my job.  IMO, Interix is an add-on to
the Windows NT operating system which provides full POSIX support.  It
is a proprietary package relying on Windows NT internals to do its job.
It certainly is a subsystem but it is also an additional package provided
by Microsoft in addition to Windows NT.

I guess the fact that the "OS supplier" itself is now providing Interix
as an add-on might be a mitigating factor.  However, if Interix was not
supplied by Microsoft, there would be no doubt, IMO, that this was a
proprietary package.

I've never purchased Interix from Microsoft, so maybe I'm wrong, but I
don't believe that Microsoft markets this POSIX library as anything but
an add-on to Windows NT.  Here's the marketing blurb:

"Microsoft® Interix 2.2 is the easiest way for customers to take
advantage of their previous investments in UNIX-based legacy
applications as they move to the Windows® operating system.  Interix
provides a powerful, high-performance environment in which to easily run
UNIX applications and scripts on the Window NT® and Windows 2000
operating systems, enabling customers to take advantage of the many
benefits of the Windows platform while still maintaining their
UNIX-based legacy applications."

But, in any event, I don't really have that strong an opinion on the
matter.  Donn Terry from Interix has contributed code to gcc/bfd (much
of it actually helps Cygwin), so, at the very least, Interix has given
something back to the community.  I'm not aware of any such activity by
whomever owns U/WIN these days.
