I don't think cynicism explains why an exec would not share the "internals" of the organization they are currently in. They are in a position of trust which has the expectation of not sharing said "internals". Betraying that trust would, rightfully, cause them to be sanctioned. Once they are out of the position, they have the option to divulge or not so some choose to do so.

Definitely not cynicism. The other way even. There is a definite amount of sociopathy and Kool aid selling needed as you guys higher up the ladder. You are a bit free from it when you leave the ladder. And forget real altruism, there is an element of perceived altruism when you look like you are "spilling the beans".
