So errrrm...am I completely out of touch with the world for not knowing who PewDiePie is (or what the incident referenced was)? Why not explain that in the beginning? There's a link later but I kind of went through most of the article blindly.
Let's Plays are videos where people play video games and commentate over them.
Fivrr is a site where people can offer small services for about five bucks.
Pewdiepie is a extremely famous youtuber who produces lets plays, and is especially popular with younger audiences. He got in trouble for playing some indian men on Fivrr to wave around signs with racist messages on them ("Death to Jews" IIRC) on camera as part of a joke. The joke was delivered extremely poorly, and even in context it just seemed really scummy. It understandably didn't go over well and lots of people wrote angry articles about it. It ended up with Disney, who were affiliated with him, disavowing him and ending that affiliation.
