Overview
Updated 1 hour agoMicrosoft's brand-protection vendor pulled Luanti's Android app from Google Play on August 27 over a DMCA notice that cited Minecraft's copyright registration and named no specific infringing asset. On September 8, Microsoft withdrew the notice, and the app went back up.
The case is Luanti's second baseless takedown in three years, and the third involving the same vendor against voxel-style games. Microsoft Research uses the open-source engine in its own AI experiments. The pattern shows how automated takedowns can silence volunteer-run projects, shifting the cost of a mistake onto the people who maintain them.
Why it matters
Automated takedowns can pull volunteer-run apps offline for weeks. Luanti got hit twice — any open-source project on an app store is exposed.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
Lenz v. Universal Music (2007-2015)
Stephanie Lenz posted a 29-second video of her toddler dancing to a Prince song. Universal Music sent a DMCA takedown, and YouTube removed it. The Electronic Frontier Foundation sued on Lenz's behalf.
A federal appeals court ruled in 2010 that copyright holders must consider fair use before issuing takedowns. The case settled in 2015.
Established that automated and rubber-stamped takedowns can violate the DMCA, though enforcement of the rule remains inconsistent across platforms.
The same machinery that yanked a mother's home video now targets open-source projects, and the burden of rebutting bad notices still falls on the accused.
Another Metroid 2 Remake (AM2R) takedown (2016)
A volunteer team spent years rebuilding Metroid II from scratch and released it free in August 2016. Nintendo sent takedown notices within hours, and the primary download links vanished.
Fans redistributed the game across multiple hosts. Nintendo never sued, but official distribution of the passion project was blocked.
Became a cautionary example of corporate enforcement unilaterally ending a volunteer project's distribution without a court order.
A large company's automated enforcement silenced a volunteer project overnight, mirroring how Luanti was briefly pulled from a major storefront without evidence of infringement.
Luanti's first takedown (2023)
The same vendor, Tracer AI, filed an identical DMCA notice against Minetest in March 2023. The app spent 46 days off Google Play while the project fought its counter-notice.
The app was restored after the project's counter-notice, but Google exceeded the statutory 10-14 business day window by weeks.
Proved the 2026 incident is a repeat pattern, not an accident, and that the counter-notice path is reliably slower than the takedown itself.
Direct precedent for the 2026 case, showing the same vendor issued the same notice with no new evidence and was withdrawn both times.
