Twitter insults aren’t impressive.
You need to lighten up. Musk doesn't owe anything to anyone, if anything he garnered interest for selling more cars to the 18 million people that watched that podcast. If the CEO of <any fortune 500 company> was on the same podcast, do you think it would have been anywhere close to as entertaining?
He owes a lot to his shareholders, and wiped 9% off the value of Tesla with that podcast. If he has to be entertaining as well as reassuring them he's also laser focused on solving production challenges - and CEO of an engineering company is definitely a job description where being dull is no disadvantage - there were certainly better ways of doing it.
Investors and board members definitely think otherwise.
I personally don't care what Elon, or anyone does in his spare time but smoking pot on TV (or podcast, basically the same thing since both are going to be broadcast to viewers) shows a willingness to take risks with the wrong amount of upsides relative to their downsides and wall street doesn't like that.
The part of it in discussion was, because of its content.
Everything that is recorded and available outside of a narrowly controlled group is effectively national TV, in that if you do something that would be newsworthy, that's where it's going to end up.
Anyone in a PR-sensitive role, including any CEO, ought to be aware of that.
