Or people can learn the rules and put on great events. I don't see how you come to the assessment that Disney used the law against someone. They simply enforced it, as is required by the law if you want to keep your protected works protected. At the end of the day, this event could have been a great success if the organizers knew what they were doing. Obviously they do need to know the details of IP rights because they got shut down. Just because something is popular doesn't mean the laws should protect it less. At the same time, nobody said that events like this cannot take place. They simply need to follow the rules.
