There's no need to fit the post into a larger narrative; it is what it is. Seems more like you may be projecting your psychology or fears onto the article. It's just a list of pricing psychology tricks. And it cuts both ways you know; readers learn how pricing strategies may affect their buying decisions.

The article is not advocating for the "manipulation" of anyone. It's up to the reader to implement, ignore or consider. If the title and some words were rephrased it could be an article on how to spot pricing tricks; the content would mostly be the same.
