>Being a decent human being is not about getting practical advantages - otherwise sociopaths would be the most helpful people around.
Sociopaths are exploiting the macro-level heuristics we've developed as a species to come to an immediate, reasonably-likely evaluation of safety, tending individuals toward trust, and danger, tending individuals toward defensive action. It takes knowledge and experience to differentiate between a good read based on sincere action and a bad read based on intentionally-deceptive action.
Sociopaths often will appear like the most helpful people around, and sometimes may actually be the most helpful people around, for the duration of the time that they need you to be on their good side. Then they'll dispose of you ruthlessly. If you don't pick up on the signals ahead of time, you don't find out until you've been backstabbed. If the sociopath is skilled, they ensure that you can't "come back from the grave" and cause problems for them.
It's not that corporations don't like cooperation in principle. From a high level, in fact, many corporations are actively and honestly trying to cultivate it. It's just that our systems keep the exploits too open to the relatively-rare maladjusted power player (normal people will sometimes flirt with the same tactics to avenge personal grudges, etc). This forces everyone into a defensive position, if it doesn't force them out of the game entirely.
Once an organ grows to exceed the direct influence of a very small handful of truly good and wise leaders (the more palatable tech word may be "visionaries"), it will inevitably mandate this weird perceptual bastardization.
