Substack wants to be seen as a pure infrastructure provider, akin to Cloudflare, but a platform can't claim to be simple software when it recommends content
Some thoughts on platforms and Nazis — Most days, this column looks at controversies unfolding on other tech platforms.
Context & Ripple Effects
Substack’s defense of permissive content rules had already been challenged after reporting found Nazi and white-supremacist newsletters on the service and co-founder Hamish McKenzie publicly resisted calls for their removal. This piece identifies a tension in that defense: recommendation is an editorially consequential product choice, not merely neutral hosting.
That distinction matters because Substack’s effort to avoid value judgments sits alongside a product designed to help readers discover publications. Its claimed infrastructure analogy is therefore tested by the role its interfaces play in distributing attention.
First-order effects
- Substack’s recommendation features become central to scrutiny of its Nazi-content policy: the company is accountable not only for what it hosts, but for what it actively surfaces to readers.
- Authors and readers evaluating the service have a clearer basis to distinguish passive publication tools from product decisions that can amplify particular newsletters.
Second-order effects
- Pressure on Substack shifts from a binary moderation question toward governance of ranking, discovery, and promotional interfaces—the mechanisms through which hosted material gains reach.
- A later partial removal policy would not resolve that broader issue if extremist publications can still be discovered or recommended through product design.
Third-order effects
- If this framing spreads, platforms will find it harder to claim infrastructure-style neutrality while operating recommendation systems; distribution choices may become the practical test of platform responsibility.
- The likely durable divide is between genuinely user-directed tools and services that curate attention at scale, with trust depending on whether governance follows that distinction.
The trend: Content platforms are increasingly being judged by their distribution and recommendation systems, not only by their stated rules for hosted material.
