      As far as whether hoarding vulnerabilities is “good”, clearly it is not! But I don’t see a plausible mechanism for KE to wipe it out. If we’re just playing “what if” then I still don’t know. It’s an honestly complicated questions with arguments both ways.

      Sure, we're talking magic-wand stuff. There is a plausible mechanism to meaningfully move the market though, such as tweaking VEP or other policies. You're correct that we can't eliminate exploits, but we *can* increase scarcity.

      I suppose my question is, to put it bluntly, are you willing to throw people trying to make exploitation harder under a bus to prevent key escrow? 😛 I think some people are, which bothers me. If you're not, then we're probably on the same page (or at least the same chapter! 😆)

      How about a third option: Being OK with the idea that some data might never be accessible to police agencies, even if it means a guilty person might get away with a crime.

      I mean, that is implicitly one of the options, right? The option I'm not willing to accept is "we don't need key escrow, because you can just hoard more vulnerabilities", because I worry that is putting more people at risk.

      Not at all, it is absolutely a risk and I don't think key escrow is a good idea. The problem I have is anyone encouraging 0day as an alternative to key escrow. That seems like protecting the ideological purity of cryptography rather than reducing risk, and gov still has access.

      You're missing the point. You can take away exploits from other people by fixing vulnerabilities, so big players committing to hoarding less exploits forcibly reduces the number of exploits held by adversaries. That is why fixing bugs is good.

      Yes, because here's the thing about exploits - you can't stop other people using them against you, your allies, civilians, etc. That's why fixing them is a good thing, and hoarding them puts everyone at risk - including the hoarder.

          Thanks! They're already supposed to be doing that, it's called the Vulnerability Equities Process, and is supposed to balance the risks. We can debate if it's working (I don't think so), but the point is there's an understanding there's a balance.
