You know how Facebook keeps saying "we never sell your data"? It was bartering it with data brokers all this time. The only reason they're even taking this step is because they know there are many other companies that could get just as much if not more data about its users as Cambridge Analytica did from the data brokers that partnered with Facebook. This would be true especially now that the "cat is out of the bag" so potentially many other malicious groups/rival states could be trying to do the same thing as CA did. Facebook simply saw the inevitable: Cambridge Analytica multiplied by 100 in its future. But one question remains: has Facebook made sure that the data brokers deleted all of the FB data, and did they just ask them to "certify" this, as they did with CA in 2015, or did FB audit these companies? (as Zuckerberg committed to do recently with all the companies they suspect of abusing its policies?) Did FB audit Palantir, too, and its use of Cambridge Analytica's data? https://www.cnbc.com/2018/03/27/palantir-worked-with-cambridge-analytica-on-the-facebook-data-whistleblower.html https://www.cnbc.com/2018/03/27/palantir-worked-with-cambrid...
