Well thats nice and Im happy for you but internet points don’t really mean much here…
What a vulnerability sells for and how much damage someone could do exploiting it are two different things. Someone capable of finding a serious vulnerability is probably capable of exploiting it themselves. They don’t need a buyer.
A company paying big bucks isn’t a contradiction. Its incentivizing disclosure over exploitation which could cost them considerably more. Engineering prioritization is… a minor part of it informed by the ease of exploitation, damage it could do (in the case of an RCE or publicly available keys as in this case quite a bit) etc.
I don’t see why you think these things are mutualy exclusive.
You think that most security researchers that can find an exploit are all willing to commit a heist with that exploit?
I’m not in the security industry but that strains credulity.
Having given up on the original argument ("Bounties exist to make it nominally more economical for researchers to report exploits than it is to resell them.") you've now transitioned to a new one: that vulnerabilities can be used by the hackers who find them to plan heists. And that is true. It doesn't set any kind of market-clearing price, and selects for actors who are comfortable ending up in prison, but it is indeed a statement that aligns with reality.
