Yeah, you can hear it in his voice. He is so anti-Steemit that he feels he can't post anything here because it somehow taints him. Like some sort of hypocritical conflict of interest created in his own mind. He could still make thousands if he came here and contributed, but he said he won't. He said he would be the last person to come here once it was proven he was wrong.
That is a sign of someone that is frankly being an idiot in this regard. It takes no effort to setup an account and test the waters. Considering his pedigree he would create a lot of interest and if he had something useful to say he certainly would be rewarded for it. He is all in on "proving" and hoping Steemit is a failure. That's not an honest position to be in.
