I don’t know much of Pewdepie and your sources are quite laughable tbh:

In one of the controversial videos, Mr Kjellberg paid two Indians through a crowd-sourcing website to hold up a sign which read “Death to all Jews”. In a response to the criticism, he said he was “trying to show how crazy the modern world is, specifically some of the services available online” and that people “would say anything for five dollars”.

It’s kinda poor taste rage bait disguised as social commentary but far from “nazi”.
