This difference is because smaller organizations are less of an entity in their own right, and more of an actual group of people doing things together (even if legally the company might still be a separate entity).

As organizations grow, they become more than a mere sum of its parts. It seems to be an emergent phenomenon driven by complexity - as humans interact, this very interaction creates something resembling an entity in its own right past a certain scale, with its own agenda (distinct from individual agendas of its constituent humans) and drive for self-preservation as a whole - the egregore that you mentioned. My pet theory is that this starts to happen when you scale beyond the Dunbar number, but the effect is only obvious at scales where most members of the organization are faceless strangers to each other.

Either way, this emergent entity is decidedly amoral.
