I'm not sure I completely agree, I don't think it's that black and white, it's a similar analogy to Guns and gun violence.
Without the prevalence of guns there is simply less gun violence, but you could argue that it's also a human problem.
Giving people who have no business using an LLM to submit slop bug bounties is a problem of the tools accessibility. But also a human problem of course.
Edit: I should mention, I don't have a solution to the problem although I do like the other posters suggestion of a "deposit" scheme to submit a bug. I think that would incentives higher quality submissions.
