Zoey, the key word here is that you are "guessing" why some family members seem to have objected to the Hughes' book. If an earlier poster accurately related what happened on Tricia's show, Chris Hughes refused to name dissenting family members. If they were all on board, the question would have been easy to answer.
I've defended the Hughes many times for many things here. I don't believe that they are greedy. I do think Travis loved them, which is good enough for me.
But....the Hughes don't "own"Travis. His story is NOT theirs, and not theirs to tell without the full permission of T's family, IMO.
ETA. The grossest injustice that has been done throughout both trials, IMO, is that the Alexanders have had to sit in silence as others defined Travis. I have no doubt that the Hughes genuinely believe they are doing a good thing by presenting the "real" Travis to counterbalance what's been said. If the Alexanders aren't fully supportive because of timing, I wish the Hughes had honored that concern and not spoken of the book until the trial was over.
If timing is not the issue, I'd like to know why the Alexanders aren't fully supportive. They've more than earned the right, as far as I'm concerned, to define Travis as they see him, if they so choose, or to give their blessings to someone else who wants to do so.
