Trisquel is what it is and its a distro for those who value the ethics of
libre software and more current software, neither too old or too bleeding
edge. gNewSense and Parabola fit the other ends of the spectrum.
Sorry, but it will most likely never be a distro for the masses. Its more of
an underground "revolution", like computing was back in the day.
Your list of concerns/suggestions are curious, however, given that are
"trying" the distro. I'm usually suspect of intentions to change when
something or someone is new.
There is no grey area for Libre v. proprietary software, it is either one or
the other. No such thing as partially free. Is a slave partially free if the
shackles are on his feet but not hands, or if he can walk the yard but not
leave the property?
