In a world where discovery is more important than delivery, it's the people who find, remix and direct attention to old stuff that should be rewarded, not the people who deliver it or sit on it waiting for someone to show up.
It's just hard. I wish the studios felt there was more value in these themes and these pieces of material - that they're worth protecting more. Because then it just wouldn't happen. If the studios cared, the stuff would be stopped in a second.
