This is pretty disastrous, the things Nintendo is suing over are things that apply to pretty much all emulators, it would be a very dangerous precedent to set if Nintendo were to win this one
And even if they don't win, it's still very shit that they're even able to use lawsuits as a scare tactic, that they can ruin people's lives even without needing to win
Also, daily reminder that "piracy equals lost sales" is nothing but corporate propaganda, often it's the opposite actually:

But Yuzu is not the thing that decrypts it. They're saying that the fact you're using Yuzu means that someone somewhere has done something illegally, and that Yuzu should be held accountable for other people doing other things.
Oh yeah I missed that, then the statement makes even less sense...
