What do the Debian people have to do with this?
I'm using the terms "free" and "copyleft" as the FSF defines them.
Do you disagree with my conclusion above?  Then say why.
Debian has nothing to do with this; the truth is independent of their opinion.
Just as it's independent of the FSF's opinion.

If we licence our material under the GNU FDL with no Invariant Sections,
then we /can't/ accept material with Invariant Sections
any more than we can accept material under CC SA, etc.
FDL w/ IS is incompatible with FDL w/o IS.
(And also with my disjunctive licence, for that matter.)

We should only go with the flow if we have reason to.
If your cookbook wants to borrow material from WP, then it has reason to.
But if my math book has no interest in that material except as information,
then it has no reason to.

I suspect that RMS will accept removing the Invariant Sections.
But I can't imagine him changing the GNU FDL to allow
redistribution under a Creative Commons licence;
since CC doesn't share the FSF's ethical philosophy
(they even offer the non-free ND and NC licence options!),
how can he be sure that CC licences will remain free?

Now, if you can get a statement from RMS saying that
he trusts CC and wants to change the FDL to allow compatibility
(presumably with CC BY-SA or possibly also with CC SA),
then I wouldn't worry about anything anymore!

Who has trouble understanding it?
I still expect that most users don't care at all.
