"a symbolic value as a precedent . As noted Matthew Ingram of GigaOm, the same protection granted to Cox could benefit, in case of need, the personality of a very different caliber, as the staff of Wikileaks, Julian Assange, and in general, all the "deep throats" that reveal secrets about Internet, as long stretches of information relevant to the community .
