The book, with it's author and publisher should be held responsible for this mis-information, whether the mis-information was intended or not.
Also, those who've purchased and are about to purchase the book should be aware that reading the book may fool you into thinking you have fewer rights.
This book may dis-empower you. Reader beware.
Maybe a 3rd-party book disclaimer service could help readers steer clear of such things.
I would start with trying to contact the author to give them a chance to correct their wrong.
