Jealousy maybe. Or frustration that marketing often seems to be more important than anything else. HN probably has more good devs than good marketers, and some of us (dev) really hate doing marketing.

A story like this seems to reinforce that just being good at product development or software development isn't enough, and that it _might_ be more effective to be mediocre at development and good at marketing. (Not to suggest that TFA author is mediocre at development.)
