So the meat and potatoes of it is back in July Substack sent out a notification to its users to “hey check out this blog”. fair enough, the problem? it was a nazi blog and the notification showed a swastika. Substack then apologized for the “errior” in sending out the push notification and stated they were going to address the issue and ensure it didn’t happen again…It didn’t apologize though for hosting fascist content, that’s fine on Substack.

So that whole thing brought to light that Substack not only has alt-right/facist content but allows it to happen. that’s what people have an issue with. Substack will literally allow you write just about anything.
