Inside Wikipedia's leftist bias: socialism pages whitewashed, communist atrocities buried

Big tech has faced repeated accusations of bias and censorship, but one platform has escaped much scrutiny: Wikipedia.

The online encyclopedia, which claims "anyone can edit", is the 13th most popular website in the world, according to Alexa's web rankings. Google gives it special placement in search results.

But critics – including Wikipedia co-founder Larry Sanger – tell Fox News that many Wikipedia pages have become merely left-wing advocacy essays.

"The days of Wikipedia's robust commitment to neutrality are long gone," co-founder Larry Sanger said.

"Wikipedia's ideological and religious bias is real and troubling, particularly in a resource that continues to be treated by many as an unbiased reference work," he added.
