Medium and Vocus can both deliver discovery, but the exchange is different. Medium controls distribution to strangers and withholds new subscribers' email addresses; Vocus handles Taiwanese payments, invoices, and member operations, but its public documentation proves only that order data—not complete email identities or payment relationships—is exportable.
Substack charges 10% of all paid-subscription revenue in exchange for publishing, payments, a recommendation network, and a shorter checkout path. Break-even depends on retained incremental value—not on subtracting 10% from the company's self-reported 25–30% network share.
Patreon charges a 10% platform fee to new creators who publish after August 4, 2025, bundling free membership, paid tiers, commerce, community, and discovery. Creators can export email addresses, but a CSV does not carry recurring payment authorization, conversations, or platform distribution.
Ghost places the site, member data, and payment relationship closer to the publisher: payments connect to the publisher's own Stripe account and Ghost charges a 0% transaction fee, but Stripe, hosting, and operations still cost money. Ghost 6 also includes Recommendations and ActivityPub, so describing it as having no discovery is no longer accurate.
Beehiiv puts newsletters, recommendations, referrals, advertising, paid subscriptions, and automation in one operating system. Official plans vary by list size and feature tier; a 0% subscription take rate does not mean zero cost or zero lock-in.
A CSV export does not mean a creator can move an entire business. Posts, email consent, membership status, billing relationships, URLs, and recommendation traffic are six different assets that require separate tests.
Creator-platform selection is not a ranking. A Taiwan-based creator should pass four gates—payments, discovery, control, and operations—before choosing a platform, managed SaaS, or self-hosted site. No CSV represents a complete reader and billing relationship.
