Hear me out: back in the day founding a company wasn't an identity, it was just an action, a verb. Stuff started going sideways when people started thinking of themselves as "founders". Suddenly the product wasn't the top priority anymore, instead it was second to defending their identity as a "founder". Seemingly stupid decisions followed, but seen from the perspective of a CEO who wants nothing more than to be a founder, they start to make sense.
We see something similar in politics, I think. Note that it doesn't apply to everyone, but it's interesting to compare people who are engaged in a social justice struggle, Vs people who identify as "activist". The latter will be very prone to doing things that are counter-productive to their started cause, because they don't really care about any cause, they're just defending their identity as activist.
I reckon the same idea holds elsewhere as well.
(Disclaimer: I'm not sure how common that last thing is in the US, but where I live, it definitely happens a fair bit. But even here it does not apply to everyone, it's just a very loud minority)
Second disclaimer: I use the word identity in a very specific way in this comment. It is not to be confused with other uses of the same word, for example in the phrase "gender identity". That is a completely different kind of identity and is completely orthogonal and irrelevant to what I'm trying to express in this comment
