Philosophy Tube has a great video about this topic https://youtu.be/rLfzO7Sbdc4. At 27:20 she starts talking about who’s life is worth grieving and who’s is not, and how this is a government level topic. It hits the nail on the head about the differences in reporting two different people’s deaths can have. At 33:45 they specifically talk about the 2008 Gaza war.

He’s had some controversial things. In 2017 he said the n-word while live streaming a game. The other big one I know of is he made a video where he showed he has paid one of those fiverr groups of Indian children to hold up a sign that said “death to all Jews”. Pewdiepie didn’t think they would actually do it.

They are really not great situations, and the second one I mentioned he should have realised was a bad idea and not done at all. Back in that 2017 era he positioned himself as an edgier meme YouTube, but he has since apologized and vastly changed his content, and i personally believe he’s a very changed person from a decade ago. But the stigma has stuck around.
