Why did the title change? It used to be the same as the original article, but now it's been needlessly editorialized to be kinder to amazon. Seriously? What the fuck. That's not HN's job, and is a disservice to the article, and the community.
But you might be right. I've been on HN for 3+ years and i've never seen anything like this happen before. This is clearly an abuse of power and is not in any way an act on the behalf of the community.
