      AGAIN: efforts to patch or disclose your way to killing exploits don't work (*cough* Project Zero). Most die from code refactors.pic.twitter.com/tXF5rFI98J

          Bounties have little overlap w exploit development. Not in skill required, techniques developed, or bugs discovered.https://twitter.com/withzombies/status/839870870545850368 …

          does that mean that increased demand for exploits by intel & LE worldwide would not affect the bug bounty market economics? @k8em0

          As much as you disagree with P0, this is an argument for it, surfacing vulns (that may be solved in clusters) and pushing boundaries
