Why would there be an anomaly? Do you really think that the thieving bastards who download them from the darknet (my apologies - "copyright infringing bastards", for the purists among us
) would have gone out and bought them if they hadn't been available for illegal download? I'm afraid I don't. I can understand why someone would download a book if there isn't an eBook version available. I don't understand at all the "morals" of someone who'd illegally download something whose legal copies are as reasonably priced as Steve's are. That seems pretty "morally bankrupt" to me.
