Maybe. Suppose a publisher lets you only view a book, and what if you want your own permanent e-copy—for work, study or recreational use on a variety of devices, some not wired into the Net. Wouldn’t you be more likely to turn to a pirate who fulfilled your wishes?
I doubt that view-only books will be beyond the skills of pirates. Technically speaking, the rule in the past has generally been: If it can be displayed, it can be pirated. I’d welcome people’s thoughts on this matter. If nothing else, pirates can scan in paper books, just as they did the Harry Potter series.
You bet the above pertains to Google. Of course, I hope that publishers will still sell downloadable books through other channels if Google doesn’t, but whatever the case, I wonder if Google might unwittingly be about to help pirates.
