It's all about that end product, it's the only thing that matters.
It absolutely is not. That makes no sense whatsoever, you're basically stating customer support is irrelevant and no service/product providers should care to properly handle their dealings, you're saying deadlines are moot so long as the end product is up to snuff and you're saying total disregard for the process in general is acceptable and to be expected.
All of the above is the polar opposite of the truth. You keep trying to inject some excitement and positivity into what has been a rather unpleasant experience for everyone involved (whether they care for it or not) in more ways than one and absolving the responsible folk of any guilt or omission when that's not what they need nor what will earn you their, or anyone else's, respect. They know they've ****ed up, just as everyone inevitably does in life, your words for a while now are not helping anyone, in fact they are damaging to the ones targeted by the scrutiny of the unsatisfied customers. I have been nothing but fair to them, I have also not felt the need to shroud their obvious disregard and my wish that they (and everyone else that takes it upon themselves to run a GB) do better in the future.
Not only are you (in)advertently doing the above mentioned, you are also passing off ill behaviour as acceptable and potentially altering the course/handling of future group buys. Mind your words, you're on an internet forum but if everyone acted the way you do buys like this would be the norm - and they unfortunately are not short in number, at least not of late. There is a crucial part of all GBs that is strictly business so please don't respond with some kumbaya philosophy about the caveat emptor and how everyone should go into a group buy expecting nothing.
Find better ways to voice your optimism that don't completely discredit your opinion(s) and influence others in less than desirable ways.
