I will agree that Facebook's controversies are a bit more egregious than most, but at the end of the day I don't really see how a random Facebook engineer is substantially worse than an engineer who works for Microsoft, or Apple, or Google, or Lockheed Martin, or <insert large corporation here>. People just want to make a decent living, not change the world.
However, I think there's plenty of blame you can place on the decision-makers at Facebook (most of the executive level team).
