Harry Potter, Fanatic about IP, accused of violating IP

The story is here. Whether Harry Potter did or did not overtly borrow from “The Adventures of Willy the Wizard,” there can be no doubt that all good fiction is to some extent borrowed from other great fiction, else there would be no point in studying literature in order to contribute to it. This story strikes me as particularly ironic since the HP publisher has been a fanatic about IP issues, confining fan fiction to dark corners of the internet instead of permitting it to be published and sold in legitimate ways. The bookstores would be far more profitable than they are if there were hundreds of HP spinoffs published, as there surely would be.
