A neutral pipeline for news? Hardly.

Well, what do you know? Michael Nunez reports at Gizmodo,

Facebook workers routinely suppressed news stories of interest to conservative readers from the social network’s influential “trending” news section, according to a former journalist who worked on the project. This individual says that workers prevented stories about the right-wing CPAC gathering, Mitt Romney, Rand Paul, and other conservative topics from appearing in the highly-influential section, even though they were organically trending among the site’s users.

...it is in stark contrast to the company’s claims that the trending module simply lists “topics that have recently become popular on Facebook.”

“Depending on who was on shift, things would be blacklisted or trending,” said the former curator. This individual asked to remain anonymous, citing fear of retribution from the company. The former curator is politically conservative, one of a very small handful of curators with such views on the trending team. “I’d come on shift and I’d discover that CPAC or Mitt Romney or Glenn Beck or popular conservative topics wouldn’t be trending because either the curator didn’t recognize the news topic or it was like they had a bias against Ted Cruz.”

The former curator was so troubled by the omissions that they kept a running log of them at the time; this individual provided the notes to Gizmodo. Among the deep-sixed or suppressed topics on the list: former IRS official Lois Lerner, who was accused by Republicans of inappropriately scrutinizing conservative groups; Wisconsin Gov. Scott Walker; popular conservative news aggregator the Drudge Report; Chris Kyle, the former Navy SEAL who was murdered in 2013; and former Fox News contributor Steven Crowder. “I believe it had a chilling effect on conservative news,” the former curator said.

...Stories covered by conservative outlets (like Breitbart, Washington Examiner, and Newsmax) that were trending enough to be picked up by Facebook’s algorithm were excluded unless mainstream sites like the New York Times, the BBC, and CNN covered the same stories.

...the Black Lives Matter movement was also injected into Facebook’s trending news module. “Facebook got a lot of pressure about not having a trending topic for Black Lives Matter,” the individual said. “They realized it was a problem, and they boosted it in the ordering. They gave it preference over other topics. When we injected it, everyone started saying, ‘Yeah, now I’m seeing it as number one’.” This particular injection is especially noteworthy because the #BlackLivesMatter movement originated on Facebook, and the ensuing media coverage of the movement often noted its powerful social media presence.

...the revelations undermine any presumption of Facebook as a neutral pipeline for news, or the trending news module as an algorithmically-driven list of what people are actually talking about.
