Davis argued that he did not actually copy any material, he only provided a link to it which opened the material in a user's media player, but the court ruled that that link broke the law.
Sounds like Davis was basically hotlinking. Delivering someone else's media to benefit his visitors, not only using another site's copyrighted material but also their bandwidth. He should have linked to the other site's page that contained the links to the broadcasts, not the broadcasts themselves.
Seems to me the judge has a pretty good grasp of "how the internet works".
