This is incorrect they actually issued dmca take down notices to about 20 emulator forks, Gary's mod content, a couple home brew projects and an out of court settlement with Yuzu. This is just recently.
Nintendo has a history of being hostile to the emulation, homebrew and modding community.
I feel like you're arguing semantics about that one emulator. At least three of those forks had completely independent teams from yuzu.
The previous commenter implied that the only hostile thing Nintendo has done recently was the yuzu settlement, which is leaving out a lot of the picture
Actually, charging people for emulation isn't illegal. The main problem, that I can figure out, is that they specifically marketed / advertised that upcoming Switch games (TotK) runs better on Yuzu than Switch. Main issue is that they did it before TotK was released.
Disclaimer: Not a legal expert, just what I could figure out from reading different stuff / articles.
