osu! never have any official beatmaps, all of the maps are community made by the players itself. Those people screaming osu are just those who don't really appreciate the song because of how good they are, they just happen to found this map and just went for a stroll on RU-vid just to say "osu!'. I'm an osu player myself, and I hate all this crap. Sorry for what our fanbase made you people went through.
