People can argue all day about the definition of 'theft' and still not come to agreement. I actually had a college instructor who thought there should be no intellectual property rights. But the simple economic problem is whether or not a business will lower prices if it doesnt feel it has to. Right now the industry doesnt even tho the economy is bad. The money it is making this season only reinforces their view.
At this point I suppose it doesnt feel that reducing prices for greater volume will help. And if their main goal is to get pirates to buy tickets why should they lower prices ever?
