GOP extortion now?

Fox own 70% of Australia's newspapers? I didn't know that, but what does that have to do with objective/impartial reporting of politics in the USA?

Because its a global issue.
You made a comment which happens to mirror a daily moan delivered by the talking heads on Fox about US "mainstream" media(even though it is mainstream itself).
A look at other English speaking places where Newscorp has a longer establishment brings balance and shows that the complaint is pretty hollow whichever side of the fence it comes from.
The media is a mouthpiece of its owners and editors and will always slant to its owners views.
There is no way round it other than government censorship or banning privately owned media.
Neither of those options is in any way desirable.
Since the alternatives are distasteful in comparison with the current model it means it is just something we have to put up with.
