Honestly, I'm surprised this didn't happen sooner. Emulating old hardware is one thing, but they have a current vested interest in their most recent console.
Still, Nintendo's lawyers can rub spurge on their eyes, and I hope the Yuzu devs find a great lawyer (or better yet, are safely hidden behind some kind of digital or geopolitical veil).
Yeah, it has always felt like we had something we couldn't wish for or expect. And it's a much better experience than using an actual switch.
Sadly the only surprising thing about this is how long it took for Nintendo to do something, I guess they worked on having as good of a chance as they could.
It would be a waste of time to litigate a case they think they'll lose, after all. Unfortunately, once the devs included proprietary code in the application, they kind of sealed their fate.
Maybe they got a little too excited over TotK and thought they were under Nintendo's radar. Maybe they felt like they owed the community an app that could play Nintendo's highly-anticipated game practically on day one. I dunno. Either way, it was a miscalculated move, and now they're reaping the consequences.
