Substack says it will remove Nazi publications from the platform

Maybe I don't understand Substack that well, but it seems like its market share would be extremely vulnerable. It's just a way to provide a newsletter (also published on the web) and accept subscriptions (and presumably they take a cut). It's really easy for someone to set this up themselves even with minimal tech skills. If they already have a following on Substack, they just tell their subscribers to move, and potentially could even import the subscriber list to a new platform. It's not like social media where there's a lot of boosting or whatever from others on the platform, so the switching costs are high.

So unless I'm missing something, I hope people who don't want Nazis around just move somewhere else. Because from the sounds of this article, they're not really doing much about the Nazis.
