Apparently, neither does Amazon, it's up to the publisher: From http://www.tierslivre.net/spip/spip.php?article2693 http://www.tierslivre.net/spip/spip.php?article2693 (a publisher against DRM): "avec ou sans DRM, ce n’est pas Amazon, c’est l’éditeur qui prescrit si oui ou non, comme il prescrit le prix" Which means It is not Amazon but the publisher that choses whether or not to put DRM, as it choses the price. Maybe it is a local policy however (as is the fixed price).
