Having youtube tutorials on something does not make you an expert on the subject. He appears to not have the skills to do basic JS debugging. It's great to ask for help, everyone needs help at some point. The issue I see is starting with "The dark side of GraphQL". If you haven't found the actual issue, how do you even know what the cause is? Just because your SQL query is fast doesn't mean there is some inherent problem in GraphQL or Apollo. That argument doesn't follow. It could be user error.

I don't mean to sound like a blind witness fanboy, but I think teaching something effectively does require some mastery of the subject.

I also don't think it is hyperbolic say he doesn't have basic debugging skills. What qualifies as basic debugging skills? Like he isn't capable of using a debugger and introspecting code? He can't use a print statement and look at code? Debugging an E2E bottleneck is not trivial.
