That's a platitude. People who work in content would say, this is about the rights of people to control the product of their own labor, and to realize the maximum value from that labor by being able to sell it to other people. That would be the same argument used by software developers when their rights are abridged by piracy, or when their code is misappropriated by (much larger) partners.
The copyright debate isn't about one industry against another, it's about an industry versus the rights of individual citizens.
