Earlier quoted context omitted.
Folks bring up the Obama comparison... because... well... its a pretty comparable situation. I'm not so charitable towards the public. I wouldn't place any bets that the striking wave of outrage directed at Facebook right now isn't strictly related to the outcome . In this case, that outcome is Trump in the White-house. Not that that isn't a good reason to be outraged - but I don't think its a very principled reason.
Pre-2016 Trump campaign, data was used to reach people and encourage voting. 2016 Trump campaign, data was used to stir up FUD and/or discourage voting.
In either case, similar amounts of personal data was harvested from facebook, for whatever purposes the clients cared to use it for, to predictable results.
EDIT: And that's all besides the point - the problem isn't that someone with bad intentions got ahold of data and used in a way they shouldn't have, the problem is people are just getting ahold of data they should not have - period.
