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.
When asked by TechCrunch about the situation, Facebook claimed in this statement it was done for corporate security:
"After Sony Pictures' emails were hacked in 2014 we made a number of changes to protect our executives' communications. These included limiting the retention period for Mark's messages in Messenger. We did so in full compliance with our legal obligations to preserve messages."
However, Facebook never publicly disclosed the removal of messages from users' inboxes, nor privately informed the recipients. That raises the question of whether this was a breach of user trust. When asked that question directly over Messenger, Zuckerberg declined to provide a statement.
[...] [Update: Recent messages from Zuckerberg remain in users' inboxes. Old messages from before 2014 still appear to some users, indicating the retraction did not apply to all chats the CEO sent. But more sources have come forward since publication, saying theirs disappeared as well.]

Just a reminder that if you keep your messages on some else's severs they can do anything they want with them. Including delete them or fill them full of goatse images.
Sure, if you jump between computers or devices a webby thingy can be handy, but if you want to keep stuff and make sure it never vanishes or changes, you should download it, and archive it off to a CD or something.
Or if it is really important, print it on good old fashioned paper. If you want to delete my printouts, you are going to have to firebomb my house! .... Uh oh, INCOMING!
