I'll give a specific (albeit still hypothetical) example:
Suppose that there are two free documents that I like,
one of which uses the GNU FDL licence, one of which uses CC-by-sa.
I want to combine these two free documents into a single modified one.
Even though both of them are supposed to be free, I can't do this!
But if either of these documents uses the noncopyleft CC-by instead,
then I am able to do what I want to do with the documents.
The CC-by licence is more free; it gives me more freedoms.
Yes, but that deals with the freedom of your use, not the freedom of the
content since the CC-by text could just as easily be made into a proprietary
derivative work while the FDL and CC-by/sa text can only ever be libre (at
least until their copyright expires, which if Disney has its say will be
never). Fixing the compatibility issue is a major problem that must be
corrected, however.
Correcting that is my plan A since it has the largest payoff in the end (a
world in which the best representation of knowledge is not controllable). Using
a license of convenience in the interim would be a bad idea since works under
that license will not be copyleft, thus making derivative works of them
susceptible to proprietary control.
