Nintendo went after a emu dev team that was actively (and demonstratively) enabling piracy for something they are currently selling. On top of that, the dev team is making significant money off of that work, to the tune of 30k/mo. Every other dev is probably thinking “finally, the other shoe drops on this obvious outcome”, most avoid making money off it, and also avoid current systems, both for just this reason. The relieving part is Nintendo’s argument isn’t about the emulator specifically, there’s nothing in the injunction stopping yuzu from continuing, and a settlement means no legal precedent.
Edit: Read more, the settlement includes stopping development.
