Facebook has finally followed through with plans to give users the ability to unsend messages, a feature it promised after Facebook admitted it had deleted CEO Mark Zuckerberg's messages from recipients' inboxes.
Facebook said its decision to make Zuckerberg's messages self-destruct was motivated by the Sony Pictures hack in 2014, after which executives' emails were leaked to the public.
Facebook's PR said at the time it limited the retention period of the CEO's messages in "full compliance with our legal obligations to preserve messages".
Still, the discovery that Zuckerberg had an exclusive unsend ability didn't look good for a company already embroiled in a public trust crisis over Cambridge Analytica, the British political consultancy that got its hands on 87 million Facebook users' data through a Facebook quiz app.
Back then, Facebook Messenger users could only delete messages in their own chats, but messages to others remained in their chats.
The Russian-linked Cambridge Analytica scammed 50 million US Facebook users for their data. The right-wing, voter-profiling company then used their information to target Americans with personalized anti-Clinton and pro-Trump propaganda.
