So that you won’t ever have to find out one day that they have written something like this to Universal Studios.
Reminds me of the Potterfan that accused Terry Pratchett of stealing the idea of a school for wizards from JK Rowling. When Pterry mildly responded that he first wrote about Unseen University in 1983, before HP was a glimmer in JKR’s eye, the Potterfan became even more incensed, huffing that he must therefore be accusing JKR of stealing his ideas.
Of course, Pterry rightly pointed out that both he and JKR were actually tapping into the great British tradition of boarding school novels and that giving boarding schools a magical twist was not original to either of them. At this point I think the Potterfan’s brane esploded.
