"But the Counter Extremism Project—an anti-extremism non-profit network based in the US—has highlighted YouTube’s continued refusal to remove Siege from its online library. 'I think it’s because they’re not taking the threat seriously,' said CEP researcher Joshua Fisher-Birch in an interview with Motherboard on why white nationalist content continues proliferating on YouTube. Fisher-Birch said he’s logged recent uploads of Siege and the Turner Diaries that have thousands of views, while several new uploads of Atomwaffen propaganda appear almost daily. The CEP researcher believes the difference between YouTube’s pronounced and well-documented banning of ISIS content versus white nationalist, has to do with its public image and business model. 'With ISIS and ISIS content YouTube was getting a lot of bad press,' said Fisher-Birch. 'It was really becoming an issue with advertisers pulling out because they were worried about their brands being associated with ISIS content. And there hasn’t been the same level of public or corporate sponsorship outrage about this kind of content.'"
