As for whining and wingeing, it probably does help the whiner/winger feel better at the time, but it doesn't change what has already happened, it doesn't make those in a position to help more disposed to do so, and it doesn't make the delivery of their 'Pi to their door any more imminent.
In short, as a pastime, it is an almost complete waste of time, effort and energy!
Sorry to labour a point and all that, but it's only a waste of time if someone at the sharp end does nothing to address the issue that caused the fuss in the first place.
It's not like the original poster was demanding that the Foundation rent the LHC for a day to create a wormhole from Cambridge to China so that the boards could be delivered last week. All they wanted was communication. It's called customer care. Yes, there are real paying customers now. It's a horrible concept, but it has to be dealt with accordingly. Really.
