The withdrawal indicates Microsoft has dropped the case and does not plan to file a lawsuit, resolving the dispute sooner than the counter-notice period would have allowed. The Luanti team also noted that Microsoft Research uses Luanti as a testbed in Project VEGA and in the paper \"Beyond Pixel Histories: World Models with Persistent 3D State,\" citing its open-source design and Lua API over Minecraft.", "body_md": "Previously, we announced that\n[Microsoft via Tracer AI had filed a DMCA notice against Luanti’s Google Play listing](https://blog.luanti.org/2026/08/27/luanti-dmca-tracer-ai/),\nalleging that Luanti infringed upon Minecraft’s copyright. The notice has been\nrescinded and the app has been reinstated on the Play Store.\n\nThe notice being rescinded means that the app has been reinstated on the Play Store sooner than if we had to wait for the counter-notice period. It also indicates that they have dropped this case and do not plan to file a lawsuit.\n\nIn a remarkable twist, after the previous post, we discovered that Microsoft actually uses Luanti for research:\n\n[Project VEGA](https://www.microsoft.com/en-us/research/project/project-vega/) - Microsoft Research & XBOX:\n\nFor the prototypes and demonstrations in this article, our testbed is Luanti, an open-source voxel game platform.\n\n[Beyond Pixel Histories: World Models with Persistent 3D State](https://arxiv.org/abs/2603.03482) - Microsoft Research & University of Edinburgh:\n\nWe prefer Luanti over Minecraft due to its open-source design and expressive Lua API, which facilitates data collection and experimentation.\n\nThese projects highlight Luanti’s potential as an open, flexible, and easy-to-use platform that satisfies a wide diversity of use cases and audiences.\n\nWhile we are glad that this situation has been resolved fairly promptly, it still consumed a fair amount of our time to fight it. We would like to thank our users, readers, and others for their support. We hope that this situation does not happen for a third time, and that future updates about the project are about new features rather than legal matters.", "url": "https://wpnews.pro/news/microsoft-tracerai-withdraws-copyright-takedown-against-luanti", "canonical_source": "https://blog.luanti.org/2026/09/08/dmca-rescinded/", "published_at": "2026-09-08 00:00:00+00:00", "updated_at": "2026-09-22 21:55:29.520621+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-research", "ai-policy"], "entities": ["Microsoft", "Tracer AI", "Luanti", "Google Play", "Minecraft", "Microsoft Research", "Xbox", "University of Edinburgh"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/microsoft-tracerai-withdraws-copyright-takedown-against-luanti", "markdown": "https://wpnews.pro/news/microsoft-tracerai-withdraws-copyright-takedown-against-luanti.md", "text": "https://wpnews.pro/news/microsoft-tracerai-withdraws-copyright-takedown-against-luanti.txt", "jsonld": "https://wpnews.pro/news/microsoft-tracerai-withdraws-copyright-takedown-against-luanti.jsonld"}}
