Exactly, that's why I said for their decisions. Like you, I've never met any of these people so who knows if they're jerks. As I've said, you can't take away her success as a producer. It's a hall of fame list of credits to her name. Unfortunately star wars is not one of them for me.
But you asked why do we have to hate them. I was explaining the why. We hate the decisions not the person. At least in mine and a few others case. Too often around here, criticism results in, I thought you were a fan, or why are you even here? It's because it's ok to criticize the decisions that are being made and still be a fan of Disney.
As far as the, they've done good things comment. I've criticized Kennedy over her decisions as much as anyone. But I've given credit for things like rogue one, mando season 1&2, and even the force awakens until last Jedi came along. I even gave props to Solo. But her tenure is littered with terrible decisions. There's a lot more bad than good. As far as Iger, I look back and compare is my experience gotten better over his tenure or worse? And that answer is a resounding worse. But again, I've given the credit where credit was due.
