But to address your underlying implication that Facebook is going down, as much as many of us would like to believe otherwise, this will blow over in a matter of weeks. Facebook will emerge out the other side stronger than ever. The outrage machine of the internet is working well lately, but it's still mostly toothless. Even potential regulator or court involvement is unlikely to result in more than a token slap on the wrist if history is any guide. People have too short a collective memory and attention span to produce long-lasting changes. Look at Volkswagon, stronger than ever after going through much harsher public outrage and regulatory action.
I'm tempted to buy Facebook stock, on the premise that people seem to be overeacting and that's always a potential for profit. I strongly dislike Facebook personally, and don't have a Facebook account.
