The Digital Markets Act (DMA), effective from May 2023, targets major tech companies like Apple, Google, and Amazon, requiring them to open their platforms to competition and enhance user control over data. While it has introduced choice screens and cross-platform messaging, some users report increased complexity in digital tasks. Critics argue that the DMA may hinder innovation and investment. The European Commission is actively reviewing compliance, with penalties imposed for violations. The law is also seen as part of a broader geopolitical context, with debates on its impact on American firms.
