TL;DR: No matter what a company does, there will always be the whiners and criers about how it's done... that being said, it's best to do what's good for the continued existence of the company.
That is exactly the problem. HF is doing what is good for HF, not for their customers. They retroactively rewrite the rules of their own game to suit their needs. Offsetting risk and losses from the company to the customer. That might be acceptable if we were investors or 'backers'. But we are not.
If you're going to have to deal with the disgruntled people no matter what, then keep the company a float so you can handle the problems instead of going out of business trying to satisfy the unsatisfiable.
You use heavily biased words like whiners, criers, unsatisfiable... But all people are asking is for HF to live up to their own promises. Nobody is asking for more than they put in. Customers will be happy to break even or take modest losses at this point. I would not call that unreasonable or unsatisfiable.
I believe that's what might be happening with Hashfast right now - they are doing the best they can in a really crappy situation.
This situation is entirely of their own making. Selectively forcing USD refunds on their earliest BTC customers while not communicating is not what I call doing 'the best they can'.
