The ‘small sin’ of wielding your userbase as a botnet is only palatable for HN’s readers because the site provides a desirable use to HN’s readers. If it were, say, a women’s apparel site that archived copies of Vogue etc. (which would see a ton of page views and much more effective takedown efforts!) and pointed its own DDoS of this manner at Hacker News, HN would be clamoring for their total destruction for unethical behavior with no such ‘it’s just a evil for so much good’ arguments.
Maintaining ethical standards in the face of desire for the profits of unethical behavior is something tech workers are especially untrained to do. Whether with Palantir or Meta or Archive.today, the conflict is the same: Is the benefit one derives worth compromising one’s ethics? For the unfamiliar, three common means of avoiding admitting that one’s ethics are compromised: “it’s not that bad”, “ethics don’t apply to that”, and “that’s my employer’s problem”. None of those are valid excuses to tolerate a website launching DDoS attacks from our browsers.
