I mean people criticize things that were never written by Tolkien/contradict the lore. Elves were never in text noted having short hair, Tolkien might never have said "Elves don't/never have short hair", but every description of them was long flowing hair.
It is just one of MANY place's where they (Patrick McKay and JD Payne) took silence as consent to do whatever they wanted instead of what was faithful to Tolkien. I find it funny how they say Tolkien is timeless, but they still feel the need to make A LOT of changes so it is more "modern".
