Yes, this is common sense. But it is "paradoxical" (or lets' just say, confounding) from the perspective of traditional economics -- i.e., it is hard to construct a model which accounts for this behavior if you consider consumers as rational actors. The behavioral economics movement -- of which the author of this article is a member -- came about to highlight the ways that human behavior is not "rational" in the traditional economics sense, and concepts such as perceived fairness or context have a huge impact.
As an aside, I didn't really read his last paragraph until just now, and thus I didn't really understand the undercurrent of anger in the comments here. I do agree that it's a foolish conclusion he makes (I'd summarize it as "bend over") and the whole point I walked away with from his previous discussion was that producers cannot expect to set prices based solely on utility; they must take into consideration perceptions of fairness and producer costs.
