It looks like he makes pitch-accent seem more important than it really is. Of course, you have to master it if you want to sound like a native, but he says he did nothing but study pitch accent for a long time, etc. Right after he’s told you how critical it is to learn it, he locks the rest of the videos behind Patreon, which honestly doesn’t seem like a cash grab.
I can’t know for sure without becoming a patron and looking further into his videos, but at first glance, it seems like he is trying to scare beginners of Japanese into buying his product. I eventually want to sound native-like, so he has piqued my interest.
