[License-review] Legacy Approval, Licnese of Jam

Given that this license does not grant the right to modify (or in US law
parlance, make derivative works), I wonder if it fails OSD 3. I think it
does, although perhaps it impliedly grants a modification right by saying
that "modifications" must be marked even though it doesn't grant the right
to make modifications?
There are other issues with this one (patent rights, which I think recently
OSI likes to see something like an express license) and the effectiveness of
the warranty disclaimer, but if it fails the OSD, it is not approvable.
