Fallout generally means something negative. If this is related to the PyCon incident (which it might not be, given that Django says they've been working on it for some months) then the "fallout" is simply the adoption of a formal document that says, in so many words, "don't be a jerk." The Django team has a right to do whatever they please with the spaces they host and moderate, and asking that users don't be jerks in these spaces is completely reasonable by any metric.
I'm assuming this is a reference to some of the after-events of PyCon. We've been working publishing this for a few months now, it's totally unrelated.
