@Humpleupagus If the company that carries out most Yuzu development loses, that has no impact on the project license.

Under copyright law, the only thing that gives permission to distribute, modify and share modified versions is a copyright license - so if the GPLv3 is unenforcable, then you have NO permission to share and/or modify the software - so you CANNOT fork - the GPLv3 is the thing you need to be able to fork.

Ninty is likely to lose, as they're going up against a business that's making a fair amount of money with dubious claims - which is a kind of party that are usually allowed to win (as freedom won't increase by a meaningful amount if that kind of party wins), just like what happened previously with game patcher sellers and those who released 3rd part titles for the gameboy.
