There's a signature difference in this discussion between
GROMACS, which is free enough that distributions can include it,
and GAMESS, which is far from it:
The license acknowledges the Gordon group's exclusive
distribution rights to GAMESS, and also prohibits you from
making copies of the GAMESS code for any purpose except use
at your own institution. Please note the distinction between
"a site license at no cost" and terms such as "public
domain" or "freeware" or "open source".
Why is it that, if you actively seek out licenses which stay out
of your way, you are a license zealot, but if you stick with
free-as-in-pizza* licensing like so much of this kind of
"academicware" (instead of, at worst, using
GPL-plus-proprietary-derivatives dual licensing), you aren't?
Academicware is just free enough to undersell more commercial,
but still proprietary, competitors and to suppress most of the
"we must replace this because it's a PITA" itch. It doesn't get
rid of the underlying cause of that sort of itch, and still
remains a form of rent-seeking. But it pushes the itch far
enough away that people don't recognize the itch as coming from
the application license.
Instead, as is done here, the problem gets recast in terms of OS
and distribution choice, and what must be done to accomodate the
application's restrictive licensing.
In a way, it parallels the "drivers: in, or out, of the kernel?"
issue. If your driver is in the kernel, everybody wins, you and
your users get help with your driver from the likes of Greg. If
your application is in the distribution, everybody wins, you and
your users get help from the package maintainer.
If, for either drivers or applications, it isn't free software,
it doesn't matter that it is free-as-in-pizza, because usability

* It occured to me, after seeing my hojillionth campus flier for
a student group interest meeting that advertized "free" pizza,
that at least some of the befuddlement the "free beer"
terminology embodies is generational. "Free beer" might have
been something people reasonably spoke of in a less litigious
time, when the drinking age in the US included, rather than
excluded, a majority of the college-age population.
