I never thought some people might dislike that part, but now I see you and a sibling comment do.
I wonder if it's good for people like me (who don't know much about music theory) and bad for people in the field. If this is the case I believe it's a good choice: the audience of non experts is much bigger and thus the minority of viewers finding this annoying will outweight the problems of those who dislike it.
So I just turn off the video and treat these presentations as podcasts. I find the audio content is informative and doesn't need the visual distraction at all.
I know several better channels for getting the theory - including analyzing genres or songs, but most are focused on instruments + theory or composing + theory.
Share one or two alt music explainers, maybe in a new submission, though here will do.

The content seems good but the rest of the presentation is just not worth getting through.
I'm not a musician, but I enjoy learning music theory concepts, and that channel for me is pure gold. I can understand half of what's said there, and still enjoy it a lot.
A couple of my favourite videos are:
