First, why do you think management is responsible for the lottery? Other than supposedly making the possibility of the best spots available to everyone, what other reason does the lottery exist from a business standpoint?
Second, I have some bad news for you; when it comes to U2, they are management.
I don't think the band push for it but management. U2 went along with it. That makes it sound that its official. I won't comment any further. Business standpoint was to satisfy the venues to stop camping out for shows. They do not want to take a risk of something going wrong outside at night. It doesn't stop people from camping out but they want camping out to be a few people not a hundred plus each night.
