Adfeno: Hi mate!
I will repeat myself for the 600th time: he who wants to install a
proprietary piece of software WILL install it no matter which distro he uses.
Some distro make it more difficult to do so, but that is another matter and
not even an important one.
All this work creating a special repo for addons it's good but it is nowhere
essential. The one who absolutely and intimately decides not to install a
proprietary whatever software will check 3 times the license of every and
each package he downloads/installs outside of the libre repository.
I can guarantee you that.
The one who hasn't made that "absolute and intimate, strongly convinced
decision" will install whatever proprietary crap on Trisquel as on Parabola
as on Debian etc etc.
I see it this way: you can not force people into freedom. I'm not saying that
implying that it is unethical (forcing people into anything could be viewed
as unethical).
But I am not saying that. I'm just saying that it doesn't work. Sadly you can
force people into slavery and dependence but you can not force them into
freedom. It just doesn't work that way. It never did. It never will.
One does not become free because he installed gnewsense or Ututo. One becomes
free when he unconditionally decides he will never ever and for no reason
install/use/share proprietary software.
