Substack expands Australia’s Online Safety Act across all publications

A Hacker News post by GianFabien announced their departure from Substack, citing the platform’s decision to comply with Australia’s Online Safety Act for every article, not merely those deemed unsuitable for minors. The writer stated they would miss many excellent bloggers who remain on the service, but refused to become what they called "yet another cog in the corporatisation of Orwell's 1984 dystopticon." The post invited other authors to recognize they too may be "exploitation targets" and reconsider their own platform choices.

Policy scope expands beyond its original intent

The Australia’s Online Safety Act was originally framed to address content harmful to children, but Substack’s interpretation now applies the requirement to all publications regardless of topic or audience. This shift means every writer on the platform, from personal journals to technical blogs, falls under the same regulatory umbrella. For a service that positioned itself as a simple publishing tool, the extension represents a significant change in operational burden and editorial discretion.

Writer response and platform implications

The departing author framed the move as a matter of personal integrity, comparing the situation to being "another cog" in a machine that echoes Orwellian surveillance. The language reflects a growing unease among content creators who once viewed Substack as a relatively open compared to traditional publishing gatekeepers. The post also hinted that the exodus could accelerate if more writers reach similar conclusions about their relationship with the platform.

Community reaction on Hacker News

The story attracted two comments on Hacker News, where readers debated the practical effects of the policy change and whether other platforms would follow Substack’s lead. Some participants noted that compliance costs and legal risk may force smaller publishing tools to adopt similarly broad filters, while others argued the move could drive creators toward decentralized alternatives. The limited discussion reflected broader uncertainty about how content moderation laws will shape independent publishing in the coming years.

What this means for independent publishers

Writers who rely on Substack for newsletters or personal sites may need to evaluate whether the platform’s new compliance stance aligns with their own editorial standards. Some may choose to migrate to self-hosted solutions or other newsletter services that have not yet adopted comparable policies. For Substack, the policy shift could affect user retention and may prompt further feature development around content flagging and reporting.
