Perhaps that HN is a rather tech-focused community, and that the other story has more relevance to most users? Or perhaps that it's a more unique story, as depressing as that thought is.
My inner cynic believes OP meant to imply that HN values technology over human lives or something similarly disingenuous, but that might be uncharitable. It could just as easily be a reflexion on the frequency of stories in this vein, that they've become commonplace, or similar.
