Well, you only need one free way to get access to external media, non-free d-i
simply add a bunch of non-free .udebs to the initrd.

This is also hinted at by the FSF FAQ, and a verbatim interpretation of the
actual GPL text. And you can proof by asburd that it has to be so, or you
start facing no end of troubles :)

The thread i linked, which is rather short, has some more legalese
