Well, truth be told if anyone decides to whistle-blow on them, Osu! can be shut-down immediately and permanently if they are actually making a profit off of that game. Donations are perfectly acceptable because it falls into the non-profit category, but if there are any advertisements on the website, or real money purchases for levels / songs in the game (this includes online 'coin' transfers like bit-coins) then that is a huge violation of copyright law and the game owners and creators can get in trouble. If they do, they will most likely get a C&D letter. In business thats typically the appropriate course of action unless there is a significant profit being earned. If they fail to comply, then they will be in court in no time.
