Just for information: the code was licensed under GPL. There is no right in the world that would allow a DMCA takedown for "being the owner of the code". If that was the case, companies wouldn't be safe to use Linux in their products.
Code can be relicensed but what's been released under gpl3 will stay that way.
Suyu, the follow-up to the popular Nintendo Switch emulator Yuzu, has been removed from GitLab following a DMCA takedown request issued by a "rightsholder." Suyu's developers' accounts were also blocked. The takedown comes just days after Suyu's first public beta release.
