According to an official statement on Ryujinx’s Discord server, developer gdkchan was contacted by Nintendo and they were offered an agreement to stop working on the emulator project, and while the agreement wasn’t confirmed yet, the organization has been entirely removed.
As I understand it, cause of the country the creator is from, a C&D was unlikely to be enforceable. Money, on the other hand, is a universal language.
C&D in Brazil stands for Comedy & Despair, where you’re the one laughing at the company desperate to get you to do what they want without having any actual legal leverage
C&Ds are generally just threats to take someone to court. They aren’t themselves enforceable.
Even I can send C&Ds if I want but I don’t have anything to back them up with. Nintendo on the other hand absolutely does.
By “enforceable,” I meant, “the reasonable legal means to follow up”.
So you wouldn’t comply with Nintendo in a similar position?
I would, but I live in a country that cares about IP laws.
I think this is the more probable version of events.
