More like pedos unable to play emulated versions of an old game Online as a public tournament and they even admitted themselves they had no permission and Nintendo warned them but they ignored it, besides there's no way to know if they used pirated ROMs or not, this isn't as simple as just proving you owning the original copy. I don't even recall any other company that promotes emulation for Online tournament contrary to what people say. (Please correct me if I'm wrong)
There's also the Splatoon tournament where even though the participants are well aware the prize pool is shit, they still participated in it and then when #FreeMelee began they "played stupid games, played stupid prizes" by having #FreeMelee on their names, thus having the tournament stream to be cancelled (not the tournament, just the stream) and then they dropped off for an unofficial tournament with a larger prize pool with like 5 digits of cash. Gets to show you where their priorities began.
The seller of the Etika Joycons was a scammer too and tried to ride on Etika and Iwata's death ("Iwata would've liked my Joy-Cons") and even tried to sue some Reddit users but hey, buy JoyCons from a scammer to own the libs evil corporate company amirite?
The worst thing Nintendo did in recent times was their stupidity to copyright strike the Nintendo soundtrack videos tbh instead of monetizing it, they didn't even release their soundtrack Online.
But hey, instead of complaining about actual issues like the limited releases for Mario 35 or Mario 3D Collection or how piss poor the collection is, or how the JoyCon quality is piss poor, they decide to riot only during the Melee one. The Etika Joycon trashfire actually got some of them even realising why Nintendo didn't want to do with their competitive tournaments because of how autistic they reacted lmao
And fun fact: There's YouTubers such as Gamexplain and penguinz0 covered the Etika JoyCon incident didn't even cover the updated information about how deep the rabbit hole went for the scammer. Gets to show how truthful they wanted.
