What about people who DDoS attack you? Is that fine? No need to have any recourse there?
How about those that hack DNS to dupe people into visiting their site etc
Those are all "Open Internet", but they're also not very nice.
I don't think it's as clear cut as some make it.
I don't know if SOPA gets it right or wrong, or if the current laws are sufficient, but I'm glad we have some of those laws in place to make the internet a slightly nicer place.
