The article isn't wrong about captivity/freedom, although alphas are certainly thing.
Hierarchies are naturally born out of confrontations and how they're settled, and captivity (ie scarcity) breeds confrontations. If two separate entities have opposing wants which cannot be satisfied simultaneously (ie are mutually exclusive), how do you determine who get's what they want? Well, naturally some kind of fight happens. Which either involves displays of intimidation, threats, arguments, or acts of violence (ie aggression).
Naturally, living organisms value life and consider risks which threaten their livelihood, and so, these situations are always an assessment of wants, such as "is my want for the last piece of food, greater than my want to avoid fighting my opponent?" Or, "Am I willing to risk dying for this? Do I need this food, do I need to fight this opponent or can I get food elsewhere before dying of starvation?".
As so, animals typically use violence as a last resort for settling disputes, unless the risks are so low as to be play (ie you're certain to win). It should therefore not be surprising that captive animals (or animals backed into a corner) feel obligated to fight, as they have few alternatives to avoid confrontation. Whereas, non-captive animals, by being more free, are better able to avoid a direct confrontation, and therefore exhibit less acts of aggression.
An alpha, just happens to be those who win disputes repeatedly, and opponents or potential opponents have learned to be intimidated by them, and so cede disputes to them when they arise without fighting. A hierarchy is thus naturally formed from repeated disputes.
