      The best part of the “going dark” debate is that we have to pretend sophisticated attacks by nation-states and criminals are some kind of Gibsonian sci-fi fantasy. It’s 2019. Theres a multi-billion dollar industry around attacking phone security systems.https://www.fastcompany.com/90307864/u-s-fund-sells-israeli-hacking-firm-nso-group-amid-spy-mystery …

      As a thought experiment, if you had to choose between a key escrow system accessible to due process (with all the risks you've spelled out) xor eliminating criminal/state access to 0day exploits, which would you choose? (I'm not making a point, just curious about your position).

      it sounds like you don't get a choice about the latter though, so you may as well just say "no" to both 😜

      Right, it's just a thought experiment. It will never happen, but if the USG committed to only using a lawful key escrow system, it might move the 0day market as billions of dollars fall out of it. Maybe that would have some benefits, but the economics seem complicated. 🤷🏻‍♂️

      Which legal systems? It’s entirely unrealistic to believe it would just be USG (just as it is any would promise and live up to promises not use zero days).

      It's not just USG, but they sure are a big player. It would meaningfully move the market for sure. They could promise not to build a key escrow system and do it anyway, so that argument works both ways I think.

      There is no “market” where governments compete for which one keeps the most promises :)

      Honestly I also think there are legitimate cases where governments need zero days to do their jobs; if they did keep their empty promise not to use them I would not be happy.

      That's really interesting, it's not governments accessing data that bothers you, it really is literally the implementation details of that access. I guess that answers my question!

      I think that is a fair summation of my position; one is at scale and largely impossible to defend against (legaly compelling) especially on a global scale and the other is natural law and impossible to prevent.

      I understand, but the counter argument would be there's no way for a government to hoard 0day without putting innocent people at risk (because you can't prevent other people discovering bugs and abusing them). This is why I don't like governments using 0day.

          if you can't sell your vulnerabilities to governments, aren't there fewer people looking for them now? so the bugs still aren't getting fixed.

          there's also an argument to be made that for each time anyone uses an 0day, the risk of 0day being caught ITW increases.

          Understood, but as a thought experiment would we need to write secure code if everyone agreed not to exploit bugs?

          I think USG dropping out of the 0day market would have a substantial market impact, and move incentives enough to improve security, but this is probably too complex to agree on! For the purpose of discussion, let's just say a treaty is signed or something. 😀
