He’s making some weird puritanical argument assuming that no parent would ever take their kids to see it based off his own personal feelings.
Keep in mind this is the same person to bend over backwards to defend Johnny Dell who was accused of domestic violence and made a payment because of it, and then in the same breath insinuated Gunn is pedophile who shouldn’t be around children (which nobody accused him of). Aka he’s just throwing crap at the wall and hoping it sticks because he’s too dug in. Not worth engaging.
Actually they were contractually obligated to Gunn because they'd already hired him for a multi-movie deal. That's why it took weeks for them to negotiate their way out of it. And yes, it is absolutely appropriate to be critical of Disney for having done it, to encourage them to be smarter next time.
