This clearly implicates that Facebook has, almost without reserve, the ability to read messages from user to user (even though it might limited to messages to oneself), and exposes that ability to its employees. You can view and search your message history on Facebook, so there is not really any question that they have and can read all messages. I never explicitly checked it but at least I never noticed any gaps, i.e. missing messages because I sent them using the Messenger app. I believe to remember that Messenger is supposed to use Axolotl Ratchet for end-to-end encryption but that is hard to reconcile with the availability of your message history on facebook.com. So maybe it's - quote - end-to-end - unquote - between the phone and the server? I never really thought about that. Or is it just not available or disabled in my Windows Phone version of the app?

It's not that infeasible to have a web platform that encrypts users messages, just each client gets an encryption key. Look at Telegram, or even FB Messenger end to end encryption. I'm not saying they ever said they didn't have the ability to do it, I'm saying it's weird that they would use "message snooping" as a form of user photo submission.

  When I send messages using the Messenger app - which is supposed to use end-to-end encryption, isn't it? - I can see and search those messages on facebook.com. Something does not add up here. And if they have the keys on their servers, then it's rather pointless to use end-to-end encryption in the first place.

    facebook only does end-to-end for "secret" conversations started in their mobile app. [1] https://www.facebook.com/help/messenger-app/1084673321594605/ https://www.facebook.com/help/messenger-app/1084673321594605...

      That explains it and it seems unavailable in the Windows Phone version. And because I never owned or used an iPhone or Android device I was unaware of this difference.

Using Messenger you can start a secret conversation with someone which is encrypted end-to-end. Those conversations only exist in the current device. But regular conversations are not encrypted in any way.

  They are sent over an encrypted transport which means law enforcement must subpoena them from Facebook, and cannot monitor them with a telephone intercept like calls and SMSes.

You can download a complete copy of the data Facebook has on you, including all messages you've sent since your account was created [1]. I did this some years ago to graph changes in sentiment with friends. 1. https://www.facebook.com/help/131112897028467 https://www.facebook.com/help/131112897028467

  Well, all data Facebook has on you that you uploaded, if other people upload your address, that's apparently their data.
