Facebook Can't Say Why Users Should Still Trust It

"We have a responsibility to protect your data, and if we can't then we don't deserve to serve you." Mark Zuckerberg wrote that in a Facebook post on March 21, at the height of the furor over Cambridge Analytica's use of ill-gotten personal information from Facebook users to help in its work for political campaigns, possibly including Donald Trump's. On Friday, Facebook announced a massive security breach--probably the most significant in its history. Taking advantage of three separate bugs in tandem, hackers gained full control of at least 50 million users' Facebook accounts. That meant that, in theory, the users could do just about anything on those accounts: post status updates for you, download your photos, send messages to your friends, download your friends' nonpublic photos, and much more.
