A kind of "they found this code, therefore you have a duty not to poison their model as they take it." Meanwhile if I scrape a website and discover data I'm not supposed to see (e.g. bank details being publicly visible) then I will go to jail for pointing it out. :(
Living in a country with hundreds of millions of other civilians or a city with tens of thousands means compromising what you're allowed to do when it affects other people.
There's a reason we have attractive nuisance laws and you aren't allowed to put a slide on your yard that electrocutes anyone who touches it.
None of this, of course, applies to "poisoning" llms, that's whatever. But all your examples involved actual humans being attacked, not some database.
