For weeks, Facebook has faced criticism for appearing to put its own financial interests ahead of the privacy interests of users in the Cambridge Analytica scandal. Now we're learning that Facebook has essentially created a two-tier system of privacy for Messenger users: Zuckerberg and a handful of other Facebook executives enjoy a limited "retention period" of their messages, whereas the embarrassing messages of ordinary users live on as long as their recipients want to keep them.
Zuckerberg has a history of having old, embarrassing instant messaging conversations come back to haunt him.

"People just submitted it," Zuckerberg replied. "I don't know why. They 'trust me.' Dumb #####s."
