re: Why give them this info?
Well ... for starters, maybe you're actually interested enough in the topic the magazine covers that you're not opposed to them passing your info along to other *related* companies? This isn't "carte blanche" permission to resell your personal info to all takers. It's more like, if you subscribe to a photography magazine, they could pass your info along to their advertisers so they could mail you advertising about new camera-related products they're offering. That might be just the type of targeted advertising you don't mind receiving?
Additionally, it's clear that this was the "make or break" deal that allowed publishers to go digital on the iPad -- so in that sense, it seems to be a good thing that half the people DID opt in for sharing their info in this manner. If nobody was willing to let them share their contact info, then they seem to feel it makes them unable to generate enough profit to be worth pursing providing the material in this format at all.

Why would anyone give them this info - you are just lining the pubs pockets when they sell your info to others.
