I don't really know why this is discussed here but I will add my two cents to it also because it is.
I stuck with Debian even if the FSF (which I am a supporter of) doesn't endorse it for the reason that it provides non-free options on its servers. The important thing for me is that Debian stays free by default. Adding non-free software should at least come with a very clear explanation that doing so means to lose the core freedoms. I don't mind making it easier for people who don't know their way around yet. In my opinion referring to a derivative distro with non-free sources like Ubuntu would just work as well as providing a non-free option in Debian directly. Debian doesn't need to be everything for everyone. I went for Debian when I started using GNU/Linux because it seemed to be the best de- central implementation of the free software vision and the base for so much else. There are many convenient options for people using hardware that doesn't have free drivers yet. In my opinion the Debian project doesn't need to include any non-free software at all. There are plenty of projects doing exactly that already and only very few take a firm stand when it comes to core values the free software movement is build upon. The Debian project could be the biggest beacon for freedom if it focused on doing the best possible with what fully free software allows.
