Well, that certainly allows "the little guy" to view the code and
extract the important parameters, math and formulas so that they can
construct their own specialized tools! Just a bit of understanding how
math is defined by a computer language and you are good-to-go.

One wonders why they converted Richmond's older code rather than NEC2.
Both are available as FORTRAN source. Even NEC4 source is readily
available these days, although not for free (so it wouldn't necessarily
meet their FLOSS objective.. I'm not sure.. they wouldn't be copying it,
they'd be converting it, by hand, to C++, and I think that would break
the "proprietary" link)

Maybe Richmond's code does insulation? or wires in a conductive medium?

the proprietaryness(is that a word?) or the copyright status may not
be broken by changing language if the algorithms are claimed as the
actual intellectual property... the code is just an implementation of
it, no matter what the language. There would be no need to convert
the fortran anyway, there are still fortran compilers available and
you could call the fortran computations from any language gui front
end. i'm doing a project like that now that calls old fortran, c, c+
+, or pascal computation modules from a new c# front end.

I would be really surprised if you could patent math formulas,
equations, etc. The software which uses them can, obviously, be
patented. Something with is "self-intuitive" or a law of nature just
can't be patented!
