  1. Sensationalist but interesting article on WhatsApp propublica.org/article/how-facebook-undermines-privacy-protections-for-its-2-billion-whatsapp-users WhatsApp moderation is a secret, outsourced to contractors, subject to errors and misunderstandings. Metadata is a gold mine for law enforcement agencies (and you can't always trust them) 1/

      Moderation is based on metadata (massive and unencrypted) plus the last 5 messages in clear, when hitting the "report" button. So the "end to end encryption" messaging has a caveat (same for business conversations) Now, the hard question: how do you handle moderation? 2/

        Options: 1) E2E encryption without moderation (Signal) 2) E2E encryption with on-device scanning (Apple iMessage plans) 3) E2E encryption plus extensive metadata with a "report" button and moderators (WhatsApp) 4) No E2E encryption and moderators (Messenger) 5) Others? 3/

          If you look for the E2E encryption options with moderation, you can read @alexstamos (former Facebook CTO) thread @alexstamos/1424054575636516867 (pro WhatsApp approach) On-device scanning is really disturbing (no wonder Apple controversial plans are paused) 4/

            If you really care about privacy, you should rather go with Signal: - WhatsApp medatada collection is abusive - WhatsApp sharing with Facebook is abusive - "Report" button is easily abused - You might not trust your country law enforcement agencies 5/

              More on this article, not only sensationalist but also misleading. A shame cause there is also a lot to learn on WhatsApp metadata and moderation 6/ @alexstamos/1435285445336715265
