Comment by ElProlactin

I think his actions speak for themselves. Facebook, effectively completely controlled by Zuckerberg, has consistently taken actions that erode privacy and degrade mental health.

And no, not every young person has the attitude that Zuckerberg demonstrated in his "dumb f...s" comment. If my son or daughter was behaving like that in their late teens/early twenties I would be ashamed and feel like a failure as a parent.
