What would be a crazy butterfly effect that resulted in the beef?

Hi. So, most of you probably know about the somewhat viral "9/11 to Ellen's downfall" pipeline (9/11→My Chemical Romance→Twilight→Actor being disrespected by Ellen→Exposses, etc.)

So I was watching a video about the videogame DOOM (1993), and in the beginning the creator mentioned how the First Person Shooter genre is about 1/5th of the games in the genre. I jokingly thought "DOOM is indirectly responsible for the beef, since without it, Drake and J Cole's song First Person Shooter wouldn't have had this name."

But on a serious note, what could be a crazy pipeline that, funnily enough, contributed to the rap beef of century? I'm really curious to see what the community comes up with. (Aside from Birdman not paying The Neptunes, I think there might be something even bigger, a butterfly effect that resulted in Birdman/Neptunes saga, or even a whole different pipeline.)
