In the past, if all the physical newspapers sold if your area had a strong bias (that went against yours), you didn't have many options. But on the internet you can easily switch to a different news source. If all the big players just start pumping out far-left propaganda, consumers can and will go elsewhere very easily.
Differing opinions are more easily accessible thanks to the internet, but the internet also allows people to more easily isolate themselves from differing opinions. In a decade, people may be intentionally consuming news from sources that are tailored to their bias. It'll be easier to hide away from news sources that express ideas you disagree with.
This is because the internet has lowered the costs of distribution and production. It has not lowered the costs of reporting...you still need actual salaried workers to report. Thus the problem. Cheap distribution has lowered the overall price, which is where the money came from to hire reporters.
The headline of the article is "The Nightly News, Not-For-Profit" and the point is this: Since companies that produce reporting can no longer sell it, wealthy donors are stepping in to fund its production in order to disperse it for free. Herb Sandler (of moveon.org) is the example given and a frightening one at that. He's a hard leftist, and is using his personal fortune to fund propaganda operations.
I always wondered what would happen to the dead trade of journalism once newspapers were gone. I guess I know now. The mild constraints that the marketplace put on pinko media owners is finished, replaced with direct orders from the Sandlers.
