Whenever there is a detailed analysis of something, it's always from one person's perspective - so there's almost always going to be something another perspective will disagree with. That's the nature of the process. There will be things to nitpick over, there will be points that aren't cogent.
But there will also be points that are. The term oriental is broadly considered problematic. The maximum intelligence, not so much in the context of AD&D overall.
One thing to consider is that any time the podcasters misunderstand something within the AD&D context (like the stat tables), you're probably misunderstanding something within the Asian reader context.
But several times the reason they stated something would be problematic to an Asian reader, it was because of how they though those fit within the AD&D context. So if the point of the video was to explain to somebody lacking the proper cultural context why OA is problematic, I don't think they made a good job.
To give you a specific example, in my native language (Italian) there is a single word denoting both eastern and oriental, so finding out that oriental has a negative connotation in US, but eastern is a (relatively?) neutral term was pretty puzzling*. I started watching the videos because I was interested in a better understanding of the issue, but most of the times I felt that they stated that something was problematic, but they failed to explain why.
* The only explanation I came up with was that given that Oriental literally means Rising, there was some association with the Rising Sun flag used by Imperial Japan, and that could be offensive due to WWII.
