I agree too, is nice to have media that respects the four freedoms. But the
issue that I see here is the position of that wiki page on what's good and
bad, and the position of Trisquel. As far a I know we follow GNU FSDG not
DSFG from Debian, so what DSFG has to say doesn't really apply here.
And GNU FSDG says:
Non-functional Data
Data that isn't functional, that doesn't do a practical job, is more of an
adornment to the system's software than a part of it. Thus, we don't insist
on the free license criteria for non-functional data. It can be included in a
free system distribution as long as its license gives you permission to copy
and redistribute, both for commercial and non-commercial purposes. For
example, some game engines released under the GNU GPL have accompanying game
information—a fictional world map, game graphics, and so on—released
under such a verbatim-distribution license. This kind of data can be part of
a free system distribution, even though its license does not qualify as free,
because it is non-functional.

So as far as I know that's the position of Trisquel concerning non-functional
data. So I agree with not including games that forbids commercial use of the
data in the Trisquel repo. However, I'm against with discourage games that
only allow non-comercial distribution of it's non-functional data. Doing that
will mean no commercial free-as-in-freedom games. I want those too, I want
people making money from their games while respecting user freedoms.
