The Disney+ model actually serves to generate income for those filmmakers with backend deals. And again, it's not about some movies as has been done on other services, it's about ALL the movies of the whole year, and without consulting anybody beforehand. When they did the deal with Patty Jenkins for WW84, they paid her a one-time fee based on how much she would have made through her backend deal had the movie made a billion at the box office, and she would have had the option to say no. There were no negotiations with, or even notice to, the creators of all those other films. Which is why all the directors, actors, unions, and agencies are so publicly pissed. As Nolan, Jenkins, and others have noted, WB used to be famous for how well they treat the people they work with, and how this move will make a lot of those people hesitant to work with them again.
