In 2019, popular Youtuber Etika sadly ended his own life. A fan decided to produce and sell custom Etika themed Joycons, with the proceeds going to a mental health focused charity. Today he announced that Nintendo issued a cease and desist ordering him to stop selling them:
Nintendo is currently trending on Twitter with 111k tweets, many of them from people who are angry at Nintendo over this, as well as other recent business decisions, such as the closing of the fan made Smash Bros Melee tournament and the Splatoon event.
Edit: It seems that the guy making these Etikons is a bit shady, Nintendo isn't looking quite so bad now.
