Never mind how many difficulty-fraught small chips, including BitFury, have also had huge problems making working miners... 
You wanna criticize Bitfury? An engineer that single-handedly designed a 55nm chip that is more efficient than most 28nm chips. Whose miners shipped on time. Whose company deals with venture capitalists instead of bankruptcy attorneys. Whose chip is powering a significant portion of the entire Bitcoin network . Go on, keep making a fool of yourself.
Stating historical facts relevant to the big/hot vs small/cool ASIC debate is not criticism. BF is obviously a self-taught engineering wunderkind. That doesn't change the fact that his first chip was tricky to get running in serial, nor the fact that it had to be underclocked to meet power spec. That he succeeded in spite of these challenges speaks even more highly of his abilities. You are making a fool of yourself by insisting we pretend everything he touched was perfect in every way. Get a grip bro, only Master Satoshi is infallible.
