      Arrogant and/or ignorant policymakers will insist the geeks "just get access somehow" which leads to more offense and less defense, which in turn makes everyone more vulnerable. It's a valid concern, but not enough to justify key escrow.

      It’s clear to me how that adds “more offense” but not clear that the market wouldn’t respond with “more defense”. Frankly having more offense get serious above-board finance might help ratchet up defense activities.

      (And love it or hate it, a lot of security companies give preferential treatment to the government when it comes to sensitive security information, so they always have an information asymmetry advantage over the rest of us.)

      Yes, but there again, they’re not a single homogenous club. There are certainly a substantial number of adversarial relationships amidst the set of wealthy nation-states, so a corresponding increase in defensive capabilities would be an expected result.

      No. I’m a pragmatist. As long as there are nations with competing interests, I think the cybersecurity arms race will be well funded on offense and defense.

      So much the better. Those are education cases. They’ll ultimately inform policy and proper risk-balancing. They’ll solidify a risk-reward model for vulnerability banking.

      You agree that two people can find a vulnerability, right? I keep getting the impression that you believe you can control who has access to an exploit, but that isn't the case.

          Any number N of parties might find the vulnerability. Given time, the probability that at least 1 more finds it increases dramatically. Any sane vulnerability bank would constantly re-asses an expiration date for the vuln to remain unfixed/secret.
