I couldn't understand your question very well, but I know its subject to some extent.
I'm *not* a member of the group responsible for evaluating system distributions, but I can try to answer this question to some extent, based on what I *currently* know (I might be wrong, please contact the people responsible before considering this as truth). As far as I can understand, Debian is not approved as free/libre system distribution because it recommends non-[free/libre] functional data, or repositories that *don't have the goal **and** accomplishment* of including only free/libre functional data. There are other freedom issues that I forgot, but gNewSense is a free/libre system distribution that's based on Debian.
