Rupert Murdoch's lobbyists found a way to transfer money from a competitor's pocket to their own. Seems to basically be it.
If the government wanted to do a tax and then support some things with the money, that'd be one thing. But this isn't going to taxpayers, this is going into Murdoch's pockets directly (oh, and Murdoch happens to support the party in power and have near-monopoly in Australian media).
