You need to understand that Burnin is just the middle man. He can't control when he'll receive the Avalon chips and he stated this clearly.  When you purchased your Avalon chips you accepted this risk. My order was delayed over 60 days. While this sucks, I don't blame burnin at all as he didn't have anything to do with this. You paid him to have components ready to assemble the boards once those Avalon chips came in. It's not like he can just go down the street and return these components as the pcb boards were probably already made up and electronic components are sold on reels typically which would have been purchased.

As far as Bitfury chips go, why shouldn't he get involved. He has a company that needs to make money. Both chip manufacturers are separate and he has no vested interest in either one besides selling fully assembled boards and turning a profit.
