Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      I don’t know what Moxie spends on Signal, but I can’t imagine that it adds up to that much on a per-user basis. Probably most of the server budget goes to pay for text messaging fees.

      So forgive me for being a naive idiot, and I realize Facebook spent something like the GDP of Paraguay to buy WhatsApp. But the idea that the only possible way to monetize e2e chat is to break the encryption and scan for keywords seems like a stretch.

      And WhatsApp didn’t grow to be a billion+ user system because Facebook marketed it. It was purchased by Facebook because a couple of scrappy upstarts managed to acquire Facebook scale — and start pulling eyeballs from FB properties.

      Anyway, my point is that Facebook already has tons of user data from its other properties, much of which is getting linked to WhatsApp accounts. Use that data to display ads. Let people opt out for a payment.

      Anyway, I realize this isn’t going to bring in the kind of revenue that FB shareholders (excepting myself!) want. But that’s not my point.

      My point is that e2e applications (even at 1bn-user scale) are alarmingly cheap to build. The threat to those apps is not that they’re *expensive*. It’s that the minute one gets successful, a giant like Facebook seeks it out and buries it in cash and a broken business model.

      I don't disagree with you but he isn't saying that *E2E* comm apps are expensive. He is saying that comm apps have a cost that must be offset by revenue - but, if they are E2E, you can't monetize the traffic in order to obtain such revenue.

      The part that *I* don't understand is the off-the-cuff remark that e2e would make WeChat-like capabilities difficult. What capabilities? Payment? Shouldn't encryption be helpful for that; not an impediment?

      Yeah. The only features I can see not working are the ones that involve server-side content scanning. Like advertising and content filtering.

      They are also probably receiving a lot of pressure from the government on content filtering. Hate speech exploding on Facebook (e.g. Myanmar etc) is a big problem for them, and they suck at managing that.

      Not claiming this is necessarily a good way, but if the e2e is signed, they can provide a way for recipient to voluntarily submit abusive/hate content for review & signature is proof tying it to sender.

          I'd assume they have a lot of scalability issues, hate speech victims (I'm not talking in the West) in Rohingya or Cameroon won't submit "abusive content for review". WhatsApp is also very popular in developing countries where those events happen.

          It is apparently a big problem in India. But this stuff has nothing to do with monetization, which is apparently the big wedge that drove the Founders out of FB.

          You mean "monetization" is the public reason the Founders drove out of FB. But in retrospection, do you want to leave because of monetization or because of Human Rights abuses? Monetization issues would not damage the stock as much as they are fairly common.

          I mean that could be true. But I doubt it.
