Regulating Platform Content Governance at Scale under the EU Digital Services Act (DSA) and the DSA Transparency Database

The European Union Digital Services Act (DSA), set to be fully implemented in 2024, represents a significant transformation in the governance of digital platforms, marking a clear shift from voluntary, multistakeholder frameworks to a binding regulatory regime backed by financial penalties of up to 6% of global turnover. At the heart of this governance structure is the Statement of Reasons (SoR) Transparency Database, a publicly accessible, machine-readable repository that catalogs content moderation decisions made by Very Large Online Platforms (VLOPs) serving over 45 million EU users. This paper explores how the DSA's mandatory transparency framework shapes the strategic behavior of globally operating platforms, maps the evolving power dynamics among key stakeholders, including the European Commission, VLOPs such as TikTok, X, YouTube, and Meta, civil society organizations, academic researchers, and EU member states, and assesses the policy's broader global implications. Drawing on an empirical analysis of 439 million SoRs and a synthesis of contemporary legal scholarship, the study reveals that 99.13% of moderation decisions are applied uniformly across the EU/EEA, indicating a preference among platforms for industrial-scale efficiency over regionally tailored governance. The case of X (formerly Twitter) illustrates how mandatory transparency measures can bridge informational asymmetries by revealing systematic discrepancies in self-reporting. Furthermore, the analysis identifies macroeconomic repercussions for global technology supply chains, including a regressive compliance cost structure that reinforces the dominance of established players while disadvantaging challenger platforms from the Global South. The DSA's 'Brussels Effect' signals a global shift towards stringent legal frameworks in platform governance, with substantial implications for digital sovereignty, multilingual content moderation, free expression, and equitable participation in the global digital economy.
