This particular article seems less about Proud Boys and more about Epik using an "alternative currency" called "Masterbucks"...
> The right wing has long accused tech companies of anti-conservative bias. Experts say the claims are unfounded.
It's an interesting situation. Facebook particularly I would say has an overwhelming conservative bias. At least, I saw an article the other day on how the top X trending posts on Facebook are always dominated by pro-conservative pieces. However, I've also seen a ton of anti-conservative partisan fact-checking on Facebook (i.e. it's obvious the factchecker was doing everything possible to label an unfavorable article as "false" or "partly false" on a small technicality). So in my opinion, the situation is that (in the case of Facebook), the userbase and content is right-leaning, while the fact-checkers/employees are left leaning and are trying to combat their own userbase.
