Oh no, a website for hackers. is hacker news a website for hackers, how about slashdot? If you are responsible for what people use your software for, even when you actively tell people not to do that, then it should also be true for guns, alchol (kids drink your bud beer, so arrest budweiser execs?).
This is one of those fundamental questions, similar to do you own physical devices or just run the software on them, like the tractors. It should be you aren't responsible for what people do with your software, if there is any legimiate use. The prosecutorial power of the us govt is very large, and they can coerce people to plead guilty to crimes where they weren't really responsible.
