The deal means that the four year lawsuit is over, but Facebook does not have to defend its actions in court. It is unclear how much it had to pay to make the case go away.

The lawsuit claimed that Cambridge Analytica created a Facebook app called "This Is Your Digital Life" that was downloaded 300,000 times and harvested users' data. The app also accessed data describing users' Facebook Friends, potentially accessing personal information of 80 million-plus users.

All that data was used during the USA's 2016 Presidential election, campaigners for Brexit, and by Russian misinformation operatives.  But, hey, nothing to worry about its not like those events had much impact on anyone's lives. 

The fallout for Facebook from the revelations includes the loss of two previous privacy cases, a $5 billion penalty levied by the US Federal Trade Commission, and a $630,000 fine levied by UK authorities.

By settling the lawsuit, Zuckerberg and soon-to-be-former COO Sheryl Sandberg avoid having to appear at their September 20 scheduled depositions.
