Well maybe in the eyes of US law, but what that's not a given for, well, me or perhaps others on HN. Take "the US highway network" for example. It can just as easily be used to transport black-market items, child porn, weapons, drugs, etc as it can transport ice cream bars. I support it. Tor just as easily supports drug sales as it does star-trek reviews. I support it.
Can't say for sure, but I think it's hazardous to assume we all prescribe to the exact same notion of the limits on free speech.
