Yes -- and HarperCollins also published little ol' me a while back, though they inherited me through a corporate takeover.

But I'm not Moore, who had several TV shows and a hit film behind him. Moore's a public figure and much easier to market. And his shit sells. Not even the Murdochites will turn away from a profit, regardless of the product.
Moore and "The Simpsons" aside, there's a definite ideological bent to the Murdoch empire which is primarily pro-US and Israeli expansionist, with a lot of flag worship and mandatory genuflections to the state thrown in.
