Because he lies. All the time.
Because he has a very clear anti-Disney bias. And he hasn't been to a Disney park in decades (or maybe he has once or twice... his story keeps changing, cf. "he lies"). And yet here he is on a Disney fan forum trying his best to make Disney look bad in dozens and dozens of posts every single day.
And he has no real knowledge of what's happening at Disney, either in their offices or parks. He just repeats what he sees posted here... but only the bad stuff (cf. "anti-Disney" bias). But he posts as if he had inside knowledge telling us the intent of executives for which he has no source.
And his criticism always comes around to the same points he makes in just about every single thread in which he participates: The stock buybacks are evil. And Iger is Evil. And the stock buybacks are evil. And Iger is Evil. And Chapek is Evil. And the stock buybacks are evil. In fact, every executive is Evil except for the good ones who are now gone and dead. And the stock buybacks are evil. And Iger is Evil. And the stock buybacks are evil.
I'm mad at people who aren't mad at him.
