The other anon mentioned the points well so I'd refer you to him.

FBT is only really used in VRC and Blade & Sorcery. For VRC it unironically helps a lot for immersion, despite that being a bit of a meme. It's also nice for dancing, you don't want to be the only disabled person on the dance floor and get kicked like pic related, do you? There's of course the gay shit too.
