Yesterday J.P. Green noted an article in Campaigns & Elections underscoring the high regard Repubican party political operatives have for Facebook as a media outlet for their ads — despite the efforts of Sen. John Thune (R-SD) to discredit Facebook as tainted by liberal bias.
But Thune’s record suggests more than a little hypocrisy, as Steve Benen noted at Maddowblog:

…John Thune says he’s concerned about Facebook’s “culture” and the integrity of its mission statement, but again, how in the world is that any of his business? Isn’t the Republican model based on the idea that the free market should decide and if online consumers don’t like Facebook’s “culture,” we can take our clicks elsewhere?
But even more striking still is Thune’s uniquely weak position. When the South Dakota Republican became Congress’ leading opponent of net neutrality, Thune made the case that any political interference in how the Internet operates is inherently unacceptable.
Worse, in 2007, Thune railed against the “Fairness Doctrine,” arguing at the time, “I know the hair stands up on the back of my neck when I hear government officials offering to regulate the news media and talk radio to ensure fairness. I think most Americans have the same reaction.”

For the sake of argument, so what if Facebook had more “liiberal” content? Fox News, Breitbart and the Drudge Report display relentless conservative bias every day, and no Senators are trying to intimidate them to change their polices to reflect a more liberal point of view. Not all media has to be nonpartisan.
But Facebook has 1.6 billion “users,” and dwarfs all other websites in some key metrics that measure influence, which explain Thune’s meddling.
In reality, however, the political content of Facebook is mostly determined by the public, as its “users” choose which articles, videos and other content to share with their FB friends. It’s different for every user, from moment to moment. Liberals see mostly liberal content, and the same principle applies for both conservatives and moderates. Facebook does provide a powerful forum for peer-to-peer political education. But everyone can choose what to read and view and what to ignore, and that includes content spotlighted by Facebook’s administrators and staff.
But Brian Fung’s Washington Post article, “Facebook is making some big changes to Trending Topics, responding to conservatives” raises a disturbing possibility that facebook is caving to political pressure. As Fung reports,

Facebook said Monday it will stop relying as much on other news outlets to inform what goes into its Trending Topics section — a part of Facebook’s website that despite its small size has grown into a national political controversy amid accusations that the social network is stifling conservative voices on its platform.
Under the change, Facebook will discontinue the algorithmic analysis of media organizations’ websites and digital news feeds that partly determines which stories should be included in Trending Topics. Also being thrown out is a list of 1,000 journalism outlets that currently helps Facebook’s curators evaluate and describe the newsworthiness of potential topics, as well as a more exclusive list of 10 news sites that includes BuzzFeed News, the Guardian, the New York Times and The Washington Post.
…Facebook’s policy change Monday appears to be aimed at defusing the palpable tension between it and Republicans outraged over reports that Facebook’s Trending Topics could be biased against conservatives. Facebook’s announcement ending the scraping of news sites and RSS feeds for Trending Topics came in a response to Sen. John Thune (S.D.), the top Republican on the powerful Senate Commerce, Science and Transportation Committee. Thune demanded on May 10 that Facebook answer a series of questions in light of the mounting outcry over the perceived bias.

Facebook has reponded that “Suppressing political content or preventing people from seeing what matters most to them is directly contrary to our mission and our business objectives.” But the changes regarding the selection of ‘Trending Topics” content suggest otherwise.
Most Facebook users will probably not notice much change in political slant and tone. That will still be largely determined by user posts. But the possibility that Facebook’s content policy can be influenced by political intimidation, especially from the politician who leads the opposition to net neurtrality, is disturbing.
