Basically, aggressive feminist groups use a hand gesture as a disrespect against men (or misogynists), but the gesture is so general and anti-feminism is so large in Korea, that a lot of people mistook the otherwise normal picture in anime/games as a hidden attack against men. It caused riots and several people lost their jobs or sometimes the entire projects/companies went down.
I think it's not a good idea to associate a very natural gesture with horrible intentions...

I imagine it's a very good idea, if you have horrible intentions.
