Disney couldn't "respond" to EU in the past 5 years because they didn't have the money to do so after:
- buying Fox
- buying out Hulu
- going 'all in' on streaming.
Both Bobs made it very very abundantly clear that streaming was the whole company's first priority (and buying Fox and Hulu was part of that). More important that their theatrical releases. More important than the parks.
It wasn't complacency.
Linear/cable TV was going to go bye-byes, and that was a huge chunk of Disney's profits. Switch to streaming or die. And so they did.
Meanwhile, Comcast invested in another gate... and... how's Peacock doing? How's NBC's ad revenue?
Disney *chose* not to "respond to EU" not out of malpractice, but for the sake of the whole company so that their TV division's profits didn't turn to dust. And by the end of this fiscal year, as their guidance promised, their streaming will be turning a profit. And that profit along with no longer having to pour investment into streaming will finance the $60B parks and experience boom to come.
