Seems like a BFL/KNC move that would cause an outrage.
With what money will their customers spend on next gen hardware when they will not ROI with their current sp30's?
I haven't put any money out of my pocket this year yet I have acquired numerous miners and I plan to buy more. It's also true that I have only cashed out around 60% of my initial investment, but I can cover the rest at any time with bitcoins. I am sure that the SP30s will help me keep acquiring more hashpower without any fiat payments from me.
So?
Who cares what currency you paid and how you made that money?
What about your customers who aren't as fortunate as you?
You can twist reality to fit your rhetoric as much as you want but it won't give the SP30 a better chance at ROI, only a ~$1500 refund or free ~2TH will.
