Regarding the first point, perhaps his subscription predates the ruination of the WSJ? The WSJ used to be an excellent paper. The editorial page was very conservative, but the news section held to extremely high journalistic standards. No one objects to opinion in a news vehicle, as long as it is confined to the "opinion section."
Regarding the issue of doing business with Murdoch: in all of his businesses, Murdoch is all about the money, at all costs. On the entertainment side of his business, it's all good. On the news side, however, we used to have this thing called "journalism": an ethic dedicated to informing the public, and an independent voice to balance the other powers in society. Today, Murdoch's "news" operations seem to believe they can make more money by dropping any semblance of journalistic integrity, confusing the public, and shoring up one specific arm of the vested political establishment. And they may be correct in that this is a great formula for profit; but at what cost to society? No one cares whether Murdoch makes money, but a lot of people are upset at his mercenary efforts to drive legitimate journalism out of the marketplace.
