I suppose the USA Today article implies it, but the only quotes they have are from the publishers, who seem uninterested in ebooks for "kids" because the ones they've tried so far haven't matched Michael Creighton's ebook sales (never mind the appeal of the HP books to adults as well as kids, or the fact that they are possibly the most heavily and notoriously pirated ebook titles ever).
Note USA Today's caption next to Rowling's image: "J.K. Rowling has been tight lipped about her lack of desire to license her Harry Potter books to purchase online." "Tight lipped," or perhaps she hasn't expressed an opinion on the subject at all? I've yet to see a direct quote from Rowling or her agent on ebooks, and her interviews are generally pretty well archived and indexed by her many rabid fans.
