Legend
Except that D&D goblins/hobgoblins have almost nothing to do with traditional mythological goblins? You might as well start calling D&D medusa "gorgons" because that's what they are in myth.
You mean the exact thing people were clamoring for when the "Male Medusa" was revealed and people talked about how they hate that the monsters are called Medusas because that is the name of a specific Gorgon?
Look, I'm not going to say "because they are Fey in myth" is the absolute best reason you could ever conceive of, but it IS a tie between Goblins and the Feywild. They are classic fey mooks, the Goblin King is either a Fey Lord, another name for Oberron, or a name of the Leader of the Wild Hunt. Just like I wouldn't say "there is no basis for changing Medusa to Gorgons in DnD" I'm not going to say there is no basis for making Goblins into Fey. It made sense when they started the process years ago, I'd already moved Bugbears into enforcers of the Winter Court in my home games, it is just something that can easily fit.
