PSR is an awesome channel and his music slaps. He doesn't give any instructions or links to files or anything else. He just shows completed examples he built that the community designed. YouTube needs to fuck off with the censorship. The information is all out there. They aren't protecting anybody.
They can do whatever they want, sure. What I will say is the moving goalposts for certain "undesirable" content is pretty ridiculous especially if you consider the history of YouTube. Several of the first partner channels and many of the oldest YT channels are gun channels. They were glad to exploit that community to build their platform, but will throw them under the bus at every turn if it can be used to virtue signal or pander to advertising partners.
