In this case it’s a specific person that has repeatedly streamed games before their release dates, meaning he’s obtaining the games early illegally and actively encouraging other people to do the same. He makes how-tos specifically with the intention of getting more people to pirate games before they release. He’s attached his real name and face to everything so it’s no surprise Nintendo probably intends to come down harder on him than that Bowser guy they reamed a while ago.
This jackass is precisely why we can’t have nice things, he’s justifying all of the bullshit reasons these companies are against things like emulation.
Except they know his real name and his face, that kind of threat doesn’t work when they can just tell your country to arrest you for breaking the law.
