"all funds raised so far will still be donated to charity"
Well, yea, because the charity was just an adjacent thing to the event. It wasn't the proceeds of Creator Clash going to charity, it was "By the way, there's a link over here for a charity if you care about that." So, obviously, if you already went to a charity and donated money to them, there's no way that Creator Clash could take your money from them and give it back to you. They never had anything to do with it in the first place, if I understand it correctly.
