Ignore that the system is rigged for the moment. I think it is safe to say these companies really like making more money. I have always wondered why then, they spend so much effort enforcing copyright laws rather than trying alternative methods to solve the problem and make more money.
E.g I know a lot of people who have some unblocking service and Netflix. Now they could increase prices for Netflix, so we wouldn't need the unblocking, but that's not on the cards. They would rather spend their efforts blocking me.
Is this purely to satisfy contractual obligations? I'd assume that any existing contracts must be in place for such a long time that making changes can't be done for quite a few years into the future and there is no realistic way to amend existing contracts. The contracts would have to cover new productions too.
Otherwise, this whole thing makes no sense to me. They appear to be giving up revenue, for no benefit to themselves.
