I am surprised that as a legitimate offering, this would even be offered for sale.

If I were in a position where I thought I'd be able to have a head start on manufacturing ASICs that blew all other miners out of the water, I'd be highly motivated to just keep it all to myself as I pretty much dominated mining.  I'd score 7200 BTC a day (with it halving soon, of course).

Or perhaps I could have my cake and eat it too.  I could sell rigs for a healthy $30k, knowing that I alone had the upper hand in deciding how productive those rigs were going to be.  If for every 10 rigs I made I ran nine and sold one, I'd effectively guarantee that all my customers were competing for 720 (360) BTC and nothing more.  The customers I sold it to would have 10x the expectations - in the end, 9x of their expected yield I'd be keeping to myself with my supply of "unsold" rigs that I was running for, um, "extensive burn-in testing" before being sold.  (What, you think I'd let them sit idle on a shelf in a warehouse?)

If this product results in centralization of mining, I bet there will be cries for Bitcoin to switch to a CPU-based algorithm!
