Depp was recenatly made resign from his roles as Grinderwald and captain Jack Sparrow for beating his former wife, Amber Heard, even though evidence seems to point to that actually Heard was beating him. But while Depp was fired from all his roles she did not get fired from a single role.
Warner brothers asked him to resign from “fantastic beasts and where to find them 3” claiming the evidence wasn’t important while keeping Amber Heard in Aquaman 2. 
Really just doesn’t seem fair
