I really don't see the point of damage control with regards to keeping AirPlay alive.  Let's face the reality of the situation.  AirPlay was doomed to failure because it was never going to fit into the narrative Koretzky was expecting.  The best thing that can be done now is to let the prominent pro-GG's say their piece and then move on.  We've already done way more that what was expected of us to keep AirPlay alive.  There's no point in wasting any more effort.
