What if there's a popular vote that declares that the Earth is flat?
Does the Earth suddenly become flat, because of that?
The DFSG is subject to interpretation and it is not possible to decide
all cases definitively by just reading the terms. Debian has set rules
to decide if a work can or cannot be considered DFSG-free (ftp masters
GR-vote); and these rules certainly does not include a consensus on
Debian legal. The argument that many works in main are under the
creative common license is a good one. One possibility is an error of
the ftp masters (and a bug report should correct it);
Unless the answer is "this is not a bug", as has instead happened for
bug #431794...
the other
possibility is a conscientious decision and in this case it can be
declared DFSG-free at least until this decision is validly reverted.
You seem to imply that a conscientious decision is by definition based
on correct reasoning and equally correct conclusions.
As if FTP masters could only be wrong when they press the wrong key on
their keyboard by mistake.
As far as I know, FTP masters are human beings and can therefore make
mistakes: both in pressing keys *and* in analyzing packages from a
DFSG-freeness point of view.
Moreover, since FTP masters do not seem to often explain the reasoning
behind their decisions, I wonder how can we understand whether they are
right or wrong, and whether we are wrong or right?
The winning option states that the Debian Project *considers* that works
such-and-such do fully meet the DFSG.
Hence, as Ben Finney said, it decided *what the Debian Project will or
will not do*: it will *consider* those works as DFSG-free.
Whether those works are indeed DFSG-free or not, is a property of the
works themselves, that cannot be changed by vote.
What if in 2008 there's a new GR that reverts GR-2006-001 and clearly
states that GFDL-licensed work are never suitable for main?
Would you say that, a work that is DFSG-free in 2007, suddenly becomes
non-free in 2008, because of that vote?!? Without any change in the
work, nor in its license terms?!?
That would be an absurd claim.
