We chose to do this so that you will be able to make personal backups of your purchased files, and so they can be converted to another user format if necessary.
But this in no way affects the copyright protection of the work, which cannot be lawfully copied so as to be given or sold to a third party. Nor can the content be reprinted without the author’s permission or reproduced in any other way that is in violation of U.S. copyright law. Please respect the author’s rights.
