Code reuse is fundamental to Free Software. I'd find disagreeing with
that to be akin to disagreeing that source availability or permission
to make changes to the work are fundamental--so far from my understanding
that I can't imagine how anyone could hold that view.
That said, my confidence in Debian's concept of "freedom" has taken a
dive just recently, and I'm much more inclined to agree that Debian
Developers may not consider code reuse important. (But the same change
in my perception of the opinions of Debian applies to the other core
elements of Free Software.)
