I post here and there and not because I am a qualified aircraft accident investigator, but I just do it to learn and express my opinion, good or bad.
When I read other people responses, I keep the good and discard the worthless opinions. From what I have seen from Captain Steeeve videos I believe, due to his ample airplane pilot experience, credentials and achievements as pilot, he can be a good Airplane accident investigator if he wanted to to become one.
His YouTube aviation accident videos run into the one half million, one million, two million and up views which tells us something. He too is giving his opinion on issues and it does not constitute an official report either!
My opinion only.
