"I'm not free because on some debian server proprietary software is hosted,
and in some installer there exists an option I don't use.
Yeah, it's clearly the lack of freedom, you're right!"
Allow me to intervene although this is my first post here. I don't think
anyone argued about whether you are using free software or not. I think the
main point to debian is whether it endangers / protects freedom. And as
pointed before the goal of FSF is not only to get people to use free software
but also teach them about the importance of freedom.
So FSF would probably agree with "running Debian using only with Free
Software" (that's what they do with gNewSense) but not with "running Debian"
because the presence of non-free software endangers the freedom of the users.
That beeing said, if I install Debian on my mother's machine, she would
probably end up running non-free software at some point without understanding
what that really means, and not even thinking about who might control that
piece of software.
PS: I currently don't run 100% free software but I'm on my way to do so, I
recently bought a ThinkPenguin Snares and requested them to donate 25% of
profit to Trisquel. I'll be moving the rest of my files and work habits from
Mint14 to Trisquel in the following months.
I will support Trisquell and Free Software community as much as I can; and
the most important I'll support software who *DOES NOT* endanger freedom in
any way.
