I am seeing people making a lot of messed up arguments about how spending money on mining equipment is a form of speculation and how it depends on Bitcoin price. It's a straw man which distracts from the real issue:

HashFast sold hardware based on an october delivery which resulted in yield projection based on a 2 PetaHash network. They failed to deliver by a significant time-span and the network is now 20 PetaHash and the yield projection is down to 10%. That right there, gentlemen, is the damage done and the only way HashFast can possibly compensate for those yield losses is by eating into their previous, current and future profit margins.
