John talked too much and did too little, that's his problem.
I don't see McAfee done little to the loss of people when evangelized the fake project for and Why do you concern him to do little when a lot of people had him back then as their influence?
well no bad deed goes unpunished either now or later, this guy did a whole lot of evangelism back then that pumped so many shitcoins. its clear he might have some shady things in his hands and this time he might not go unpunished. whatever you do, always stay clean.
It clear he had a lot of shady things in his hands cause if he can evangelize for a project not caring about the consequence there's a possibility that he might secretly be among the project team.
