... unless you own the derivative work because it is a "compilations of
preexisting works"!

A typical large open source Software would be exactly that -- code,
documentation, and other works that are, and I quote, "selected,
coordinated, or arranged in such a way that the resulting work as a
whole constitutes a new work". The fact that some of the Software pieces
belong to the open source Project itself and some were obtained/licensed
from external sources is probably irrelevant here -- the Project can
still claim the copyright on the "compilation" or "collective work".
