It must _allow_ derivatives to be open source.
!= It _forces_ all derivatives to be open source.

Look at the BSD licence, it's the best example. It allows binary-only
distributions to be BSD licenced thus "open source" (well, except that
there's no source which could bear the trademark). We had this already.
