I think that part of the problem for them is that around the time of the Oprah interview they were kind of holy, nobody really wrote anything bad about them, everything they said was believed.
But now, after the TV series and the book, notes can be compared and all PH says is clearly not the truth. Sometimes it's not even his truth, it's just wrong. And then Meghan having to admit to the court that she'd colluded in Finding Freedom...
And then the lack of delivery on the $$$ deals.
It has all added up, and now the gloves are off. Which leaves people asking what they are actually for now, how is their stance of "global this that and the other" actually backed up?
