Earlier quoted context omitted.
If there's no duty to consider potential harm when releasing tools, then why would there be a duty to avoid criticising people who release them?
But if such things exist in secret and there's neither awareness nur a reference implementation to develop countermeasures against, wouldn't that also cause harm?
Importantly though, that aim is served by proofs-of-concept and information sharing more than it is by releasing point-and-shoot attacks. This comment puts it rather well [1].
As above, I'm not saying this shouldn't have been created, or even that it shouldn't have been released. I am saying that there are important ethical considerations and questions raised that should be addressed directly by the creators, rather than being handwaved away as in the quoted disclaimer.
