"there IS no answer" Sure there is. 'In the begging' it was was invariably led by some kind of founder/owners, and the values of the company were intimately related to their values. For better or worse. A public or widely held company not led by founders tends to have a more political class of executives who are more likely to report to the board on the basis of 'making them money'. Maybe not, but probably a little more so than otherwise. Every situation is different. So the answer to 'why' is simple: the board probably makes the expectation of the CEO, who requires that of the team, one way or another, and that trickles down into various plans of various kinds. It's really just that.
