How is this not a violation of Sherman anit-trust legislation? Sometimes metaphors for the internet/cyber world don't map well to real worl past examples. But this instance aligns very well to Standard Oil's transport rebates for their own oil. Oil is to content as railroads are to networks. IANAL but until the US starts enforcing anti-trust legislation this kind of thing will continue to happen. Net neutrality doesn't stand a chance against these kinds of behemoth ISPs and their lobbyists.
