The problem is that we can't take your agreement or disagreement at face value. The OP that prompted this entire thread admitted, front and center, that their $400k total comp number was very seductive. People do and believe all sorts of things when their fat salary incentivizes them to do so, even if they don't consciously realize it.
What's that Upton Sinclair quote? Ah, yes: "It is difficult to get a man to understand something, when his salary depends on his not understanding it."
I recognize that it might not seem fair to take this position, but understand that it's an easy one to take when I look at FB's negative effects not just on the world, but on the lives of actual people I know. It seems unlikely to me that a disinterested party could truly weigh FB's positives and negatives and think the balance is positive. But you are far from unbiased, and I hope you can at least realize that.
