You can’t remove Facebook messages from the inboxes of people you sent them to, but Facebook did that for Mark Zuckerberg and other executives.

Facebook chats sent by Zuckerberg from several years ago or older were missing from the inboxes of both former employees and non-employees. What’s left makes it look the recipients were talking to themselves, as only their side of back-and-forth conversations with Zuckerberg still appear. Three sources asked to remain anonymous out of fear of angering Zuckerberg or burning bridges with the company. None of Facebook’s terms of service appear to give it the right to remove content from users’ accounts unless it violates the company’s community standards. While it’s somewhat standard for corporations to have data retention policies that see them delete emails or other messages from their own accounts that were sent by employees, they typically can’t remove the messages from the accounts of recipients outside the company. It’s rare that these companies own the communication channel itself and therefore host…
