If people used emulators for homebrew there wouldn’t be much of a fuss about it. But they don’t, they use emulators for piracy.

It doesn’t matter if it has legitimate uses if 50%+ of the information online is about piracy and game dumping.

Nintendo is gonna care and they’re gonna try to stop these things, so long as their primary use is piracy. It doesn’t matter that there are legitimate and legal use cases. There are zero people writing homebrew of any real value for any console platform newer than the SNES as far as I’m aware. There are lots and lots of toy applications in homebrew stores but nothing serious. LOTS of detailed and useful info about how to pirate games, though.
