I'm not blaming the researchers for anything. They did the research, found a
major issue, and got a reward in line with the published expectations, and have not complained about it being too little. Why would I blame them for any of that?
It is only uninformed HN posters imagining that vulnerabilities are worth millions of dollars on some imaginary black market that are complaining about it. Just like they do with every vulnerability disclosure that mentions the size of the bounty.
And by repeating this low-value conversation for the hundredth tube, you (yes, the specific you) are just hijacking the conversation and taking attention from what is unique and interesting about this case into your fantasy grievances about the bounty being too small.
