>The practice of creating blacklists for certain types of sites or searches has fueled cries of political bias from some Google engineers and right-wing publications that said they have viewed portions of the blacklists. Some of the websites Google appears to have targeted in Google News were conservative sites and blogs, according to documents reviewed by the Journal. In one partial blacklist reviewed by the Journal, some conservative and right-wing websites, including The Gateway Pundit and The United West, were included on a list of hundreds of websites that wouldn’t appear in news or featured products, although they could appear in organic search results.
Gateway is trash and I'm not sure what United West is but they can't say they aren't blacklisting political sites at this point. Pretty big challenge for them ahead of the bipartisan AG investigations and 2020 elections.
