The video about the East German chip industry is well researched. Making the chip industry investments responsible alone for the collapse of the GDR is a bit click-baity (it was at most one contributing factor).

As factual and valid as you could hope for. I find his work very thorough.

Here's a video about China's Gallium & Germanium Export Controls:

I didn't find it anti-China, neither are his other videos in my opinion.

According to the transcript below Jon Y. is half Taiwanese/Hong Kong, make of that what you will.

Can you provide some examples of content you felt was anti-China propaganda / brainwashing?

If it matters, in an interview he had, he said he thought China would successfully... reunify with Taiwan if it tried, and iirc, that it would happen eventually.

I think a lot of people in the Asian geopolitical theater just really don't like China because they do a lot of crappy things.
