A normal purchased ebook can only be used on the account it's purchased with. A DRM free one could be emailed to all your mates, uploaded, torrented, etc
Whether that would really have a material impact on sales is of course another matter.
Sure, i understand how DRM works and my assumption was that the free ebook would still be to the purchasers account and protected in line with industry standards etc...
