I see how easily Hbomberguy can be hated, with the shit-flinging anti-semitism and alt-right stuff, but the point were pretty easy to understand:
-Internet Historian stole the script for his video, word for word
-After that, sneakily didn't tell anyone what the problem was, and tried to reupload it by rephrasing some segments.
-None of the rephrasing made it not plagiarism, it was the most basic shit a high school student would do.
-Crediting on the reupload doesn't make it not stealing. You wouldn't want a person of socio-economics to steal your bike, even if he paints your name on it to give credit.
Fucking retards somehow still say that putting the credit in makes it not plagiarism when he just jacked that whole shit. That's not how citing things work.
