I have a different opinion, but it is just my opinion.
I think the sudden departure of Chapek (after they renewed his contract in June for 3 years), the sluggish performance of Disney in the stock markets, the lackluster performance of Disney studios, milking the parks like a golden goose and the public dissatisfaction made them ripe for a potential hostile takeover.
Apparently there was even a study to see how much it would take.
American companies are often targets in the international corporate raider scene.
They are not out of the woods yet, even with appointing Iger as CEO.
