I've worked in infosec at a FAANG and large corporate environment, and the amount of eye watering stupidity I've seen from brand new employees is difficult to reconcile with the prevailing theories about the level of intelligence they hire. It's like they spawned into a whole new universe and don't have any understanding of what is expected of them.

Humans do not always act in their rational self interest.

I guess people would spy on those they know and the answer is curiosity.

Not all of these people would have been engineers, some may have been support people or account managers.
