I agree that this comment is frivolous based on the assumption that reading HN comments is about gleaning knowledge from the community. I love a great contextual joke, but not in the wrong place.
If you hate Amazon's practices there is more reason to study them because of their success. Every successful company that's done a pereceived evil has also tapped into a market advantage that led them to their success.
If you hate Amazon learn why they succeed and build better. Dismissing everything they do well because of what they've done wrong leaves the advantage to everyone who sees nothing wrong in draconian business practices.
