I don't really understand this argument: if GitHub allows hosting things that completely disclaim warranty and people are using things from GitHub, don't you effectively have this "tossing a blueprint into the world" problem? Sure, you aren't entitled to it, but there are plenty of places that offer this kind of service and plenty of consumers who get software from these services.
