"A Substack spokesperson referred the Guardian to an essay published on Wednesday by the platform’s co-founders, Chris Best, Hamish McKenzie and Jairaj Sethi, in which they said silencing vaccine sceptics would not work. “As we face growing pressure to censor content published on Substack that to some seems dubious or objectionable, our answer remains the same: we make decisions based on principles not PR, we will defend free expression, and we will stick to our hands-off approach to content moderation,” they said."
