And I'm the one making "baseless assumption"
So according to your baseless assumption, were Frank's book and all his appearances on TV and various events promoting the book, also part of the contract with the Estate? Did Estate put a clause in the contract that he has to do all that and talk nice about Michael? That he has to appear in David Gest movie The Life Of An Icon and talk nice about Michael? That he has to defend Michael on his private Twitter account after LN was released?
At least my "baseless assumption" is logical and make sense while your baseless assumtion is borderline conspiracy theory.
