Y Combinator (YC) has urged the Trump administration to endorse Europe’s Digital Markets Act (DMA), which targets anticompetitive practices among major tech firms. The DMA identifies six 'gatekeepers' including Apple and Amazon, imposing restrictions to promote competition. YC's letter, shared by Public Policy head Luther Lowe, emphasizes that the DMA aligns with American innovation values. They argue it opens opportunities for startups while curbing Big Tech's dominance. YC also highlights Apple's delays in AI advancements as a lack of competitive pressure affecting smaller ventures. The administration's response remains uncertain.
