I think you need to breathe a bit and then re-read my comment. I’m not coming at you, I’m saying that what an exploit sells for and what it could cost a company if exploited are entirely different things. That’s where you’re hung up.
Companies have an obvious financial incentive to encourage discovery and disclosure before exploitation.
I’m not in the security industry but that strains credulity.
The point is that bounties create an incentive to find and disclose vulns. That doesn’t require a black market for the exploits.
I’m responding to this. I would assume the list of people able to find a vulnerability is much much greater than the number of people willing to do a one off heist with it.
