Sure. But “they have skin in the game therefore the analysis is invalid irrespective of any actual criticism of the content of the analysis, which I have not bothered to mention” is OP’s insinuation, not mine.
I’m just pointing out that that cuts both ways. If there’s a problem with Markopolus’ report it should be critiqued on its merits. OP didn’t bother to bring any of that forward and just focused on shortselling.
