Bitmain could be trying to crush the competition as their miners are now much cheaper than all the other miner manufacturers and the efficiency is about same as all the others have caught up.
I suspect thats part of the reason. But things can still work out somehow. The D3 was bad but the antminer A3 was well handled. The first A3 batch users have already broke even. I hope that all miners will be well handled. The fact that they give out coupons and gave fair options to early X3 buyers also tells me they can find solutions too.
Just my 2 cents.
