Primary data for Phases 1 and 2 comprise European Commission synopsis reports supplemented by the Staff Working Document (SWD [2021] 84 final). Phase 3 data draw on the analytical report commissioned from the Centre for European Policy Studies (CEPS, 2025), supplemented by original analysis of anonymised raw response data (n = 383). The DSA pre-legislative consultation (July–September 2020, n = 2,863) provides a contemporaneous benchmark. Industry aggregates company/business organisations and associations (Phases 1–2) or providers, deployers and industry organisations (Phase 3). Under alternative aggregation treating SMEs separately, the large-corporation and industry-association share still exceeds 30%, maintaining industry plurality by a factor of more than five over citizen participation (5.74%). The headline finding is robust to reasonable alternative aggregation decisions
