That is so vague and unsubstantiated. I don't come to that conclusion from looking at this article. How easy is it to replace conservative with liberal? It seems very likely.
Don't mistake the majority of the whining for the majority of the censoring. The left-wing equivalents of Gateway Pundit aren't included in Google News, either (and they shouldn't be, to be clear). You just don't see Democratic Congressional reps complaining about that fact in bad faith.
>Google has said in congressional testimony it doesn’t use blacklists. Asked in a 2018 hearing whether Google had ever blacklisted a “company, group, individual or outlet…for political reasons,” Karan Bhatia, Google’s vice president of public policy, responded: “No, ma’am, we don’t use blacklists/whitelists to influence our search results,” according to the transcript.
How do you feel about Google lying to you?
The supposedly blacklisted sites like Gateway Pundit are still in Google's search results. They're just not deemed news outlets included in the News tab.
Same reason my small business doesn't show up in the Finance tab. I'm not blacklisted, I'm just not eligible for inclusion.
