"Respond" in what sense? If GitHub has any plans to address the issues outlined in the "Dear GitHub" letter, there's nothing stopping them from writing their own letter saying "We hear you, we're working on addressing the following concerns, and it's going to take approximately this long before you see results". Unless I've missed it, there's been no response at all from GitHub; if they care, why don't they say so?
