A later note from RMS:
In the interview, I said that all the BSD systems " include, in
their installation systems--in some cases I believe it's called a ports system...--they all include some non-free programs". What I meant is that the non-free programs are included in the set of programs that the ports system can install. The ports system software as such is free. For me, distributing a recipe to fetch and install a non-free program is pretty much ethically equivalent to distributing a copy.
