I only watched a few minutes but I didn't see anything objectionable. I was getting annoyed at the people he was talking to. It seems to me, you either know what the answer is so state the answer and the evidence, or you don't, so state that you don't know and express your plan to find an answer and return with it.
Once I hurt my back, had to drive for three hours, park far away, hadn't eaten all day, and when I stopped at a restaurant, having hobbled there with my bad back from a distant parking spot, the hostess was absent for ~5 minutes and when she finally showed up she was distracted and talking to other people multiple times while I tried to get an answer to how long the wait would be and if I could get served. So far, I've lived a fairly easy life, and I've always tried to be polite and even keeled - but in that moment of discomfort, tiredness, hunger, and disrespect, I genuinely wanted to be rude to the hostess.
The point of the digression is, I imagine that's what being the CEO is like, only it's not once. It's every day. And the more committed you are, the more hours you subject yourself to this kind of thing. You just want things well documented, bugs fixed, quality high, you want people to answer questions etc. When you've been dealing with this all day for decades - I can see how easy it would be to be a bit impolite.
