I think this news story speaks for itself. (Yes, the whole "Raven's Bride" kerfuffle has now drawn the attention of the Associated Press.) Such a response is sad, but given St. Martin's overall attitude, not unexpected. However, judging by the response it's been getting from the online community, I suspect this "see no evil" tactic will backfire on the Flatiron Building, sooner rather than later.
In response, all I can do is offer some more words of wisdom from Mr. Poe himself: "To attempt the rebutting of a charge of plagiarism by the broad assertion that no such thing as plagiarism exists, is a sotticism, and no more."
