They never said that. They said that they didn't want to use the Grinch for being too Seuss. It's because his world and such was already used up in Dr. Seuss's battle. It'd be too similar. Superman and Batman are from the same fictional universe. And they've shown interest in using Harry Potter. The difference is that some characters are too close and similar to ones used, so those shouldn't be used, but if they have enough material that differentiates them from said character, that's good.
