Besides the Ellison story, Shooter says Mantlo would swipe other stories, with another big issue being that Mantlo saw Barry windsor-Smith's Hulk backstory that explained a history of abuse as a child by his father. He saw pages of it and depending how you saw it, either decided to implement that into his run figuring it was fair game since it was going to be introduced later, or just plain decided to take the story.
BWS was insulted by this and would leave Marvel due to it, taking the story with him and reworking it over the next 40 years into a graphic novel.
