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.
