Unnecessary.

People have been screaming to get her fired for over 5 years. Trouble is, she has friends in high places, and she "knows where the bodies are buried," in a manner of speaking. She apparently knows some dirty secrets about people high on the foodchain in Disney, and if they try firing her and severing her contract before the alotted time, she'll basically "burn the place down" by revealing their dirty secrets to the world.

However, Iger has come up with a plan that the bitch can't squirm out of. If there's one thing a movie studio hates, it's losing money, and Kathleen Kennedy has been responsible for billions being lost, due to her horrible films and the shitty Star Wars tv shows that have been put on Disney+ in the past few years. It's caused many people to give up Star Wars altogether, all thanks to her. Iger has been carefully building a case where she has been an extremely irresponsible studio head, doesn't know what she's doing, is incompetent, and was not fulfilling her end of the contract by earning Disney/Lucasfilm money. He's going to use that horrible Indy 5 film as evidence of her incompetence, and use it as an excuse to finally get rid of her, as well as making her pay out of pocket for the money lost on a film that's already over budget, so no golden parachute for her upon "retiring."

One way you can tell the "announcements" were BS by KK is because none of those films had been greenlighted, and just about everyone in the studio was caught off-guard, totally unaware such movies were going to be made at all.

Based on the studio's past history, chances are high these monstrosities will be canceled and nothing will come of them. There won't even be concept art made of them, let alone any script rough drafts.
