Whether it's the big guys in this world or the companies that make billions of dollars, if the legislation is clear, they'll sit at the bargaining table. If they have a right to release or licences to obtain from certain people, or with respect to the assets they use, they will be at the bargaining table. As an aside, this is why management and other companies exist. In fact, grouping the rights holders within these companies brings bargaining power.
The problem lies in the number of exceptions in the Copyright Act. How do we change things and make sure that the big guys of the world can be at the table? It's simple: you have to make the legislation and their responsibilities clear.
