However, to act as if different interpretations of folklore pre-existing Tolkien's work aren't allowed to use the name elf (even though Tolkien had originally adopted the german words Elb and Elben until they didn't stick with his audience) is kind of childish.
This game is an excellent example of how this is not childish, including copyright strikes, lest everyone ends up as a cannibalistic slave giraffe, driven by sensationalism.
Maybe you can see the irony in how an incorporation of certain elements (like slavery) makes them more generic than any ear shape could ever achieve. Again, the complete opposite of creative or unique. This was also visible in Dragon Age, where the so called elves are basically the "oppressed natives".
I'm not 100% on Tolkien's side either btw, but his elves don't violate canon.
