Nintendo doesn't care. They stay in their lane and they are strategic about each move.

I remember hearing about pretty terrible corporate culture as they demand obedience and swear you to secrecy. I think I remember some guy mentioned he worked at Nintendo on a podcast and they instantly fired him to make a point.

What Nintendo does care about is knockoffs. At their core they are toymakers who make collectibles. What is a knockoff? Anything that Nintendo deems so.
