I would ask what law grounds the definition of the black box. If one would try to do the same to a illegal content hosted on a website, where should I start drawing this box? At my ISP, since it is the edge where I as a customer receives the content? At the websites ISP, since it is the one that broadcast the content? The coo-location of the server, as it is there that the mechanism for broadcast is happening? The hardware, which produced broadcast? Or is it the person who acted on the machine in order to create the broadcast?

As with a onion, each layer covers the internal workings of the next one. The actual functionality being provided (ie content) is the same at each step.
