Well, what that means depends on your view of the maxim that "all publicity is good publicity". I'm sure more copies will be sold. I'm also sure more copies will be read with a more skeptical eye than normal. And for many of us, the quality of her review, the specificity, especially to critical and basic factual errors, tells us a lot if we find her believable (helpfully she cites two other reviewers making the same claim). For me, that's enough to decide not not buy it.
