So, why is this allowed?

So, there's a name I want: Farore (Zelda was my childhood, and almost everything I do is named after it, even my current name, Sciela). Looking the name up, it has literally no games minus one or two a season (and it only shows four games in season 5, nothing before or after) to keep the name from being available, but Riot won't unlock the name even though it's clearly not being used.

My question is why is that allowed? That's really just asinine of that person, and I don't know why they just allow it; most companies would just unlock the name since it has no activity at all, and obviously isn't being used.
