Substack—Substack initially refused to remove pro-Nazi publications after writer open letter, then removed five under sustained pressure
After The Atlantic's November 2023 reporting documented explicitly pro-Nazi newsletters on Substack, more than 200 writers signed the 'Substacks Against Nazis' open letter in December 2023 asking Substack to enforce its own content rules against Nazi publications. CEO Chris Best and co-founder Hamish McKenzie initially refused, framing Nazi content as protected speech and saying removal would not make hate disappear. On January 8, 2024 Substack reversed course and removed five explicitly Nazi-affiliated publications while leaving others online. Major newsletters including Casey Newton's Platformer departed the platform in protest.

Substack removed five Nazi-affiliated newsletters after open-letter pressure, Platformer departed in protest
Casey Newton's Platformer (which originally surfaced the Nazi-content reporting) documented Substack's January 8, 2024 reversal removing five explicitly Nazi-affiliated publications after weeks of public refusal. Platformer announced it would migrate off Substack in protest of the limited remediation.
