I don't see mention of it in the article but Leftbook (a subculture of left-leaning Facebook groups) is a major reason why leftists continue to use Facebook.
"Leftbook" is small groups of far-left people. This article is talking about news articles being spread across Facebook, which seem to be fake right-leaning conservative "news" sites.
Also, FB's community standards seem designed to stymie conservative and right wing speech.
You can attack the rich on FB, but not those so poor they receive welfare. You can attack people based on their 'privilege' but not on their immigration status.
