Yeah, I totally agree. But on the other hand, if Fireman Rick's job is to put out the occasional small wildfire, and one day a small controllable fire starts but Fireman Rick says not "not my problem, I'm gonna stay home and play video games" and then that fire burns down half the state, there's a sense in which the fireman is to blame by choosing to abandon his job.

Or to give it more of a HN spin: if Rick's job was to run a website, but hackers broke in and stole all the plaintext passwords, it could be construed as partially Rick's fault for negligently storing the passwords in plaintext, even though the hackers were the ones directly responsible for the hack.
