Unless D'angelo has some expensive eight figure lifestyle, he's not going to a poorhouse anytime soon.

> He was chief technology officer of Facebook, and also served as its vice president of engineering, until 2008.

> D'Angelo was an advisor to and investor in Instagram before its acquisition by Facebook in 2012.

That depends on the amount of damage you cause.

You think he could be personally liable for eight figure plus damages?

Where is the precedent for this?

There is no precedent for this because it is utterly unprecedented. No board in the history of boards has - as far as I know it - acted in such a way that they ended up outright annihilating the thing they were supposed to be governing with total disregard for the consequences. That's not normal behavior, it is so far outside of the norms and rules of conduct for board members that it may well shape those rules and create new legislation.
