I don't believe it was to show that Vertoe was shady...please reread what was posted as vertoe actually seemed to not like how the "Dash insiders" were operating hence he made several posts saying why he was not going to continue being involved in dash.
As i am one of the "Dash insiders": Do not expect to much.
Vertoe left because he did not agree with the vision/goal the team had for Darkcoin/Dash and he disliked the organizational structure the project team had back then. He made many code commits, did lots of work and came up with ideas for improvements - which did not get the attention he wanted to have. When he was left out on the discussion/decision on the Dash name change he was totally pissed and rage quitted. The rest is history.
I always respected his decision to leave the team and will continue to do so - though the style he chose to quit was inappropriate: He deleted work created by other volunteer team members, did some rant posts (the ones you are refering to) and finally passed his BCT account to others.
Some positive side effects: Some of his main critic points have been changed since then: The number of people who have admin access to github is >1 now and some (not all) of the centralized code (reference node) has been removed.
So.. i am looking forward what shady secrects will be revealed.
so what is the "big thing" vertoe is referring to? who are the fishy people vertoe mentioned?
