I mean, it really is as simple as you'd think it is.
They're entitled, vain, and incompetent.
Gigantocorporate structures... do that to themselves and their constituents.
They have a whole other kind of 'social norms', just like any particularly culturally different group or economic class of people have noticably different expectations and behavior patterns.
The corporation values ass kissing and gaslighting more than anything else, it takes an extreme and constant, consistent effort inside the company to make that not happen, like pushing a boulder up a hill.
You can place varying degrees of blame on management or devs, on specifically full of themselves and insufferable people...
... but the ultimate reason this happens is because shareholders say line must go up, and the social dynamics that occur in an organization that is rabidly aiming for that goal... produce narcissists that are full of themselves.
Because a mass shakeup, an attempt to reset that via resetting people... well that means downtime, that means 'a rebuilding year'... but that line needs to keep going up NOW. And firing all your top leadership is a near guaranteed way to tank your stock value.
So, the most influential people with the most wrongheaded ideas fail upward, untill the money printer breaks, and then, at that point... shareholders are okay with firing leadership, because the bad thing, the line go down, that already happened.
