@vriesk @chris @bsdphk first, I'm not a lawyer, and you do have "before the law and on the high seas you're in Gods hand".
Given that bag of salt, I'd assume their customers could sue them. Also other service providers that sold services could be sued by their customers, but they could not sue the contributing company as long as they had no "maintain that software for me" nor "I bought thingie and it came with that software" relationship.
Anyone differing on that reading?
