The morally incorrect action in this article was downloading an e-book from a torrent site (that was not sponsored by the book author or publisher and not authorized by them or linked in any way to purchase of a physical book). If an author or publisher choses to make an e-book and physical book available for a single fee, that is their choice, but that is not what was described here. So I don't see a dilemma, just an act of piracy.
