I agree they had creative battles, which to me is exactly why Feige didn't want to deal with Whedon anymore, especially as he already had the wheels for Civil War and what came after in motion. I don't think this was an "abuse" situation as much as a "I am tired of this dude" situation. Mostly though, I think it is telling that Whedon clearly lied with the AoU situation and is clearly lying here. So taking his word on these matters feels impossible at this point. Dude's a obvious liar, and not an elegant one. That he used COVID as a crutch here is embarrassing as hell imo. P.S. I don't know if the Russos, Markus and McFeely are yes men or not. They do seem to actually get along with Feige, which is probably a good thing. What I do know is the story they crafted by them from TWS through Endgame was pretty terrific, and I preferred them to Whedon by a lot.
