Beyond speculation. Nintendo is known to not fuck around, thanks to its leaks.
In one of the various Nintendo leaks in the past few years was a bunch of documentation of "Operation Belgian Waffle", their attempt to "Knock and Talk" with a private investigator, law enforcement, and Nintendo Legal visiting a fairly well-known hacker in the scene. All of this was being spearheaded and commanded by Nintendo of Japan towards the subsidiaries in other countries.

Nintendo was already operating inside the Discord as per screenshots of evidence in the case, so they really had some leverage here.
