I never even thought about that, latropa. Although, the pages on your hard drive are not being redistributed. That would be the bigger concern to me, is that google freely distributes the information to whomever wants it.
I guess it'd be like me copying some pages of a book in a library to take back and study, and me copying those pages, making a few hundred copies, and giving them to whoever sent me a self-addressed stamped envelope.
