It frankly asinine to object to work around hacker ethics as "off topic" at such broad hacker conference. Is Appelbaum's 29c3 keynote "off topic" for asking hackers to work for the "good guys" rather than military, police, their contractors, facebook, etc.?
Yes, obviously harm reduction is a psychological hack that need not involve a computer, but this holds for "social engineering" as well. It's simply that hacking isn't nearly as specialized or inaccessible as say theoretical physics.
Worse, there is no shortage of terrible technology laws like the CFAA, DMCA, etc. that exist partially because early hackers failed to communicate an ethics that seemed coherent and reasoned to outsiders.
