I mean, there is a mix here, some genuine notes about how high bounties can cause coordinated breaches to farm income but also notes about how bounties shouldn't replace pen testing (I agree, but have both and don't, as a pen tester, just argue that more money should go to pen testing, it's way too self-serving) and a weird comment that having a low bounty and then overpaying for a return of privileged data if the compromise could expose that data is a bad idea because it encourages bad actors - if the bounty is 3k and the data is worth 30 mil then yea, bad actors will emerge because you're criminally underpaying for exploits.

Honestly, a lot of the reasons I'm seeing for lowering the payout of bounties seems to revolve around "It's too expensive"
