Have you considered the possibility his whole YouTube gig was always a scam? Look at how 1995 his website is. Has ever done a video teaching how to do anything technical so viewers can do something themself? He's a talker. There's no evidence of having IT skills.
His audience is the uninformed, don't know any better. All he does is talk. People are better search videos and watching a random person showcase how the work is done for people to follow along and teach through examples. Rob doesn't show anything, only talks about it.
For all viewers know, all of his videos might be his opinions based of what others say, but give him a terminal or a shell and a keyboard, he might not know how to do anything.
