To survive, if the whole model of the citizen-miner survives, these companies are going to have to do things differently and develop non-hateful relationships with their customers. KnC seems to be leading the way. HF is working to follow. At least that's my bet.
The road to customer goodwill for Hashfast seems pretty clear to me:
1) Offer full refunds to batch 1 customers.

They may as well do that and many on this thread would be surprised with the results. Accepting the refund means you are giving up additional 2TH for free on Feb 1st. Good luck buying those 2TH with refunded BTC for less, considering end of Jan/beginning of Feb delivery. Maybe the refund is safer way, but I bet many people would not accept refunds. They bought miners in the first place because they don't want BTC sitting in their wallets. Announcing MPP starts Oct 30th changed many things.
