I don't see a need for correction.
Someone can try to repeat what Howey describes, but it won't be exactly replicated, if only because Amazon is often tweaking how it presents data to its customers.
I mentioned the anonymous source thing tongue in cheek because, while it's possibly true, it doesn't feel that way. Don't authors, as a class, like to draw a bit of attention to themselves? Few would want to do so much work and then pass on all credit to someone else, while completely losing control of how the data is used. In a real collaboration, there are multiple credited authors.
I'm not saying the article is bunk. But I group it closer to punditry than science.
