I'd do this if I were OP. There is nothing to lose. It certainly seems to me as a non-lawyer that if the facts are as they are written it would be at their discretion. Perhaps the original deal won't be honoured but a token payment for good karma could happen. It could still be significant given the numbers involved. I would personally have not named the companies in a post on HN though. I suggest the OP edit this if they still can.
