As of now, the U.S. Copyright Office is still publicly pointing to the May 2025 pre-publication version of Copyright and Artificial Intelligence, Part 3: Generative AI Training, not to a formally effective final AI-training rule. Even so, the policy debate has become much more operational over the past year. If commercial model training continues to rely on platform datasets, open-web scraping and third-party licensing, questions about data provenance, authorization chains and the execution of rightsholder opt-outs are no longer abstract talking points. They are turning into concrete compliance issues that companies may be asked to explain.
For short-video platforms, social media services and other UGC-heavy businesses, the real pressure is not just whether a front-end “no AI training” option exists. It is whether that instruction can actually travel through scraping controls, API outputs, data-sharing arrangements and downstream development workflows. The Copyright Office has not publicly issued the kind of finalized mandatory technical rule described in your topic brief, but the direction is already clear: a platform that enables AI training access while struggling to show how opt-outs, license scope and protected-content filtering are implemented will have a harder time presenting itself as a neutral conduit in future copyright disputes.
