I'll tell ya why he resigned, because he is a respected person in the industry and he knows BCLI is nothing but a sham. I never liked their "new" CEO...who is in fact their old CEO...and I suspect never really gave up that role. Tony got out before his career was ruined by the snake oil salesman.
And to be clear - this is not a "New" CEO, he's been controlling the puppet strings from day one. Fiorino was brought in to display some sense of legitimacy, now the curtain is once again pulled back to reveal the original snake oil salesman.
