In September 2025, Alison Roman announced she was moving her 343,000-subscriber newsletter off Substack and onto Ghost. The following month, Anne Helen Petersen — one of Substack’s most prominent writers and a recipient of one of its six-figure development advances — left for Patreon. Lyz Lenz followed, citing bot subscribers artificially depressing her engagement metrics and Substack’s algorithm pushing what she described as “rage, Nazis, transphobia, and conspiracies.” Within two weeks on Patreon, she recovered 70% of her paid subscriber rate.
These were not isolated cases. According to one industry piece tracking the space, Beehiiv saw nearly 3,000 creator migrations from Substack in the twelve months to March 2025. Ghost has been the destination of choice for publishers seeking control over their brand and technical infrastructure, while Patreon has absorbed writers primarily motivated by content moderation concerns and audience quality issues.
Taken individually, each departure has a specific rationale. Taken together, they expose something more structural — a tension at the heart of the “own your audience” promise that the newsletter platform era was built on.
What “owning your audience” actually meant
Substack’s original pitch was a direct response to the social media era’s broken promise. Facebook and Twitter had taught publishers an expensive lesson: build on someone else’s platform, grow an audience there, and watch the algorithm change the terms until your reach collapses. Substack offered an alternative framing: your email list belongs to you, subscribers are yours to take, and the platform is just infrastructure.
This framing was — and remains — partially accurate. Substack does allow writers to export their subscriber lists. Migrations to Ghost are technically straightforward; Alison Roman was able to move 343,000 subscribers without disrupting a single subscription because both platforms process payments through Stripe. The email list, in a narrow technical sense, is portable.
But portability of a list is not the same thing as ownership of an audience. And the migrations of 2025 reveal exactly where the gap lies.
The writers who can leave Substack and take their audiences with them intact are, almost without exception, writers who had already built the kind of following where “your audience will follow you anywhere.” They don’t need Substack’s discovery engine. They don’t need the Notes algorithm. Their readers subscribed because of who they are, not because Substack surfaced them.
For everyone else — the majority of publishers on the platform — the audience relationship is more entangled. Growth on Substack increasingly runs through Substack Notes, through the platform’s recommendations engine, through algorithmic amplification that rewards certain kinds of engagement. One writer described being told by Substack’s partner success team that posting three times a day in a specific way was necessary to please the algorithm. The email list may be portable. The growth mechanism that built it is not.
The fee problem compounds as success grows
The economics of Substack’s 10% cut are designed to feel reasonable at the beginning and uncomfortable at scale — which is precisely when it matters most.
When a writer has 50 paying subscribers at $8 a month, the $40 that goes to Substack is an abstraction. When that writer has 2,000 paying subscribers at $8 a month, the $1,920 monthly fee is the cost of a platform that, increasingly, competes with their own content for attention through its social features. As one writer who migrated to self-hosted Ghost noted: at 100 subscribers paying $10 a month, Substack is already taking $100 monthly — more than flat-fee platforms charge for lists of comparable size.
Ghost charges a flat monthly fee regardless of revenue. At meaningful subscription revenue, the financial case for migration becomes straightforward arithmetic. Ghost’s own comparison calculator illustrates the point starkly: a publisher with 1,000 paying subscribers at $5 a month generates $60,000 in annual revenue, of which Substack takes $6,000. Ghost’s flat fee at that scale is a fraction of that.
Brad Hargreaves, who ran Substack’s highest-grossing real estate newsletter, moved to Ghost in September 2025 not primarily for fee reasons but for capability reasons: he needed API access and webhooks to integrate courses and database products into his publishing business. Substack’s closed platform couldn’t accommodate the business he was trying to build.
This points to the second dimension of the ownership problem. Substack’s infrastructure is optimised for a specific kind of newsletter publication. Writers who want to evolve into more complex businesses — courses, databases, memberships with multiple tiers, custom integrations — eventually hit a ceiling. Ghost, as an open-source platform, has no comparable ceiling.
The moderation dimension that platforms won’t resolve
A persistent thread running through the 2025 departures is content moderation — specifically, discomfort with sharing a platform and a recommendation engine with writers whose content many independent publishers find objectionable.
This matters beyond the ethical dimension. On Substack, the recommendation engine connects publications to potential subscribers across the platform. A writer’s newsletter can be recommended alongside, or in opposition to, content they find harmful. The platform’s Notes feed surfaces posts from across the ecosystem. For writers whose audience relationship is built on a specific set of values, existing within a platform that monetises and algorithmically amplifies content antithetical to those values is not just a philosophical problem — it is a brand positioning problem.
The Nieman Lab’s coverage of the October 2025 departures noted that this wave of exits also cited email delivery failures and absent technical support as practical grievances. The “Why I’m Leaving Substack” post, as Nieman observed, has become a genre of its own — and the reasons have evolved from the early days of “10% is too much” toward a broader dissatisfaction with what the platform has become as it scales.
What the migration pattern actually reveals
The uncomfortable truth embedded in all of this is that “owning your audience” has always been more conditional than the newsletter platform era implied. The email list is the asset. But the relationship within that list — the trust, the engagement rate, the subscriber’s habitual attention — was built partly through the platform’s infrastructure and partly through the writer’s own work. Separating those contributions is harder than exporting a CSV.
The writers leaving Substack for Ghost in 2025 are, in the main, those who have accumulated enough independent credibility that the platform’s contribution to their audience relationship has become marginal. They can migrate because they have, over time, made the Substack infrastructure increasingly irrelevant to why their readers subscribe. The writers who cannot leave so cleanly are those whose growth is still entangled with the platform’s discovery and recommendation systems.
This is the dynamic that every publisher building on any platform eventually confronts. Substack is not uniquely culpable. The same analysis applies to any platform that offers distribution in exchange for a share of revenue or audience data. The terms look generous early, when distribution is the scarce resource. They look different once a publisher has built something that the platform needs as much as the publisher needs the platform.
For bloggers and independent publishers, the lesson is less about which platform to choose than about what “owning an audience” requires. A portable email list is a starting point, not a destination. The actual asset is an audience relationship strong enough that readers would follow the publisher anywhere — across platforms, through migrations, regardless of which algorithm is currently in fashion.
Building that is slower and harder than optimising for a discovery engine. It is also the only version of audience ownership that cannot be taken away.
