I get it from their perspective, featuring dwarves in a game doesn’t really help others find similar games in the same vein. On the other hand, they have a tag for pirates and Black Flag differs quite a bit from puzzle pirates.
Wouldn't a ninja tag technically say more about a game than a dwarf tag though, since a Ninja is a profession, meanwhile dwarfs are just short creatures fond of drink and industry?
This is the original meaning of the phrase "the customer is always right". It's been warped by "karen" types into a weapon used against minimum wage workers, but what it's supposed to mean is "the customer is always right in matters of taste". Meaning if a company doesn't want to do something because they think it's dumb but the demographic says "I like that" then the customer is right, and the company should do it. I know the dwarf tag isn't about money, but it's still a matter of listening to the customers on the platform.
