Summary

Canadian author Naomi Klein has launched a newsletter on Substack, despite criticism from tech reporter Karl Bode that the platform coddles white supremacy. The platform has become a major market for independent writers and journalists in Canada, with over 1 million subscribers worldwide. However, concerns have been raised about the presence of hate speech and AI-generated content on the site, which has led to the introduction of an AI detection tool called Pangram. Critics argue that Substack is prioritizing the promotion of AI-generated content over addressing its issues with extremist content.
