The article, as Dom has already pointed out above, is 99% of what the deal concerns. JTs content was made for Tubes. It performs best on Tubes. The affiliate side was "doing his head in". Biggest problem with having wildly popular content is... dilution. This deal helps solve that problem, and at the same time further increase (yes, I know this seems a paradox to some!) the control JT has over his content on the big Tubes while removing the headache of managing the affiliate side of things. Seems like a great deal for JT too me.
(* - The other 1% (actual $$ amounts etc) will, obviously, only be known between JT and Manwin. As it should be.)
