Facebook denied the accusation of spreading anti-Semitic tropes regarding Soros, saying: “To suggest that this was an anti-Semitic attack is reprehensible and untrue.”

Freedom from Facebook hit back at the social network.

“If anyone knows about spreading vile propaganda it’s Facebook and if they are hiring Republican political operatives to launch false attacks against the Freedom From Facebook coalition, clearly they are concerned about us and, judging by their stock price and employee morale, they should be,” Freedom From Facebook co-chair Sarah Miller said in a statement to Fox News. “But nothing more perfectly summarizes our policy case — that nothing will change at Facebook unless the FTC and Congress act — than everything Facebook has done over the past year, as laid out in this New York Times piece.”

A Definers spokesperson told Fox News the company is “proud” of its partnership with Facebook and that all of the work it did for the tech giant is “based publicly-available documents and information.”

At the conclusion of its blog post, Facebook says it still has “a long way to go” but cites a range of measures it has taken in the two years since the 2016 election to improve safety and security and battle misinformation on the platform. Fox News reached out to Facebook for further comment on the Open Society Foundation’s letter.
