What are the DMA and DSA?
The DMA and DSA are two European regulations that took effect between 2023 and 2024. The DMA imposes obligations on giants designated as gatekeepers: interoperability, choice screens, no self-preferencing. The DSA governs content moderation and the transparency of large platforms.

Europe long watched the tech giants settle in without a word. Then two regulations arrived, taking effect between 2023 and 2024. The DMA (Digital Markets Act) targets the economic power of the biggest players, designated as “gatekeepers”. The DSA (Digital Services Act) deals with content: moderation, targeted advertising, algorithm transparency.
You already see their effects, often without knowing it. That screen asking you to pick a browser or a search engine when setting up a phone? That is the DMA. The obligation for dominant messaging apps to open up to competitors, or the ban on a giant favoring its own services in its results? The DMA again. The transparency reports of large platforms and the easier reporting of illegal content come from the DSA.
These texts complement the GDPR, which has protected your personal data since 2018. And the penalties are anything but theoretical: the fines imposed on Google in Europe run into billions of euros.
Where it plays out: the law can constrain the giants, not choose for you. The book offers a complete method, the DÉCLIC method, to take back control service by service.
