AI-generated

This summary was generated by AI from the original report to make it easier to scan and cite. It is not a substitute for the source — read the original above.

Written by Lisa Macpherson and Morgan Wilsmann, this policy primer lays out a framework for how policymakers should approach free expression and content moderation given recent shifts in the media, technological, political and legal landscape.

Rather than presenting original empirical research or platform-specific data, the primer is a conceptual and policy-oriented resource: it reframes the terms of the debate over platform moderation, addressing how legal frameworks, changing political pressures and evolving technology intersect with questions of speech online. It positions itself as a reference document for legislators and regulators navigating content moderation policy in a landscape that has changed substantially since earlier moderation debates.

Its overall aim is to equip policymakers with an updated vocabulary and set of considerations for content moderation, rather than to advance a single specific legislative proposal or empirical finding.
