For some other companies that for some seem to be 'cool' to hate, the gaming media loved to share horror stories and rumors of crunch, bad working conditions or harassment, or complained regarding lack of inclusivity between their characters or employees. Even in cases like Quantic Dream where after several trials and administrative investigations the court and government said they weren't guilty/are innocent of all the stuff.
But for Nintendo I don't remember any story, this is the closest one I remember. Workers and execs at Nintendo are humans, so I assume they may also have proportionally the same issues than the other companies, both inside and outside gaming.
But well, knowning how harsh is Nintendo with people taking down rom websites, videos of their games, fan games, blocking Smash tournaments and so on I assume their legal & PR team maybe is very aggresive with these topics too outside of how open is gaming media to throw shit at Nintendo with these things.
