I didn't see the note on the page, thanks for the correction. However it says

Item Under Review This book is currently unavailable because there are significant quality issues with the source file supplied by the publisher.

The publisher has been notified and we will make the book available as soon as we receive a corrected file. As always, we value customer feedback.

Which has nothing to do with the lawsuit or book published. It's more about the electronic formatting having errors
