The Obama campaign did not break their contract with Facebook. While I generally agree with the rest of your comment, Obama did in fact break their contract with Facebook. The developer TOS said that any data obtained through the API was to be used exclusively for the purpose of the operation of your app. Unfortunately, by all accounts, they used this data for purposes outside the app, such as campaign strategy and voter targeting. Further, this was back when targeting Facebook ads by ID was allowed. So they likely did far scarier things than either Trump or Hillary were able to accomplish. We don’t know, because the media was OK with his win, and as a result, nobody investigated the specifics.
