I never read the article in question, but I was able to find your answer as soon as I looked it up. It is the first subsection of the article which begins "The lycanthropes presented in the Monster Manual can’t be injured by physical weaponry..."
Probably any fight between lycanthropes is a non-leathal brawl. They can go as all out and as hard as they want, but their healing factor is going to kick in.
Until someone of them submits. Mechanics wise the rules aren't going to support this and were never designed to because lycanthropes are monsters to fight players and arguments among lycanthropes are plot devices for the GM to fiat.
Not sure if this was added after you read the article but the issue is addressed in a manner:

This has the unfortunate side effect of making all lycanthropes immune to the natural weapons of other lycanthropes. You can approach this problem one of two ways:
Treat it as a worldbuilding element. What happens if lycanthropes can’t be harmed by one another? Do they form uneasy truces? Do they always fight nonlethally and bring ropes and chains to bind foes they’ve grappled? Do lycanthropes keep silvered weapons on their person to defend against other lycanthropes, or is that too dangerous? Do lycanthrope clans instead keep a single silvered dagger locked away in their camp, and use it to ritualistically slaughter the enemies that they drag back to camp?
Create a workaround. Simply declare that lycanthropes’ natural weapons bypass their immunity to bludgeoning, piercing, and slashing damage. Or, declare that lycanthropes natural weapons are magical, and thus overcome any creature’s resistance or immunity to nonmagical weapons.
This encounter presumes the second option, in order to make this encounter more broadly usable. However, if you want to customize this encounter to your campaign setting, it may be more interesting to choose the first option and start creating werewolf lore for your setting.
Even before this article I was of the mind that Lycans can harm each other with their natural weapons, however, it would require catastrophic damage to actually kill it. If Lycans fought each other, the damage would be with resistance, they would regenerate the damage slowly (10/round) like Trolls, and due to this the "catastrophic" damage requirement. At 0 they fall unconscious but they still aren't dead. It would require multiple other Lycans attacking in unison to tear the downed Lycan apart.
The article that was on the front page was entertaining but after rereading the rules didn't make sense.
Werewolves are immune to B,P,S, normal non-silver attacks.
Werewolf attacks are not magical or silvered.
