Sort it out mate, and pronto. as so far it does not wash, and this is more than the odd thousand dollars someone could just remain angry about. The beef surrounds people's livelihoods, you stand to ruin people.
You're right, of course. But the grim fact is, he doesn't have to do anything. The unfulfilled orders, the trade ins, the refunds, the chip orders... it will all soon be forgotten collateral damage.
I didn't read the original source, but this page refers to Batch 5 sales. That's all that has to be done: advertise Batch 5, for a good price. I did read the intention that preorders were going to be a thing of the past. BFL Monarch shows that's not necessary; muppets will still clamor for a picture and a promise.
Maybe it's true that taking preorders and then having to deal with whining when they're not fulfilled creates too much dissonance for a narcissist. In that case, maybe it will be sales from stock. Either way, though, the best expectation to hold about these past issues is no expectation at all. Then, if something is done, be pleasantly surprised by the largess.
Until then, simply say the Bitcoin miner's mantra: "it was not more than I could afford to lose" over and over, and then, when Batch 5 comes out, buy one to go with your Monarch order.
