Companies aren't the source of truth, but they do represent a floor of acceptable behavior for people working together in a group.
To give a counter-example: in my observation, in academia (in particular math and physics departments), there is a lot more tolerance towards excentric traits than in companies - and collaborating in a group nevertheless works.
Thus, companies are an insanely bad example to define a reasonable floor. Rather, the traits that are considered acceptable in companies are whether they are useful for making the company money. For example dark triad traits can be useful for that, so such traits are somewhat accepted in companies.
