I'm confused, we all know that Facebook has been biased for leftists for a long time.
If these leftists are now opposing Facebook its not because there is any support for conservatives.
The only thing I can think of is these extreme leftists want Facebook to go all in with suppression of non leftist opinions and facts they do not like.
Purhaps Zuckerberg has refused to destroy what little deniabilty of non bias is left by going that far.
Or maybe this is all false propaganda to try to make Facebook seem more neutral than they are.
