If you want to share something, then share it. If you don't want to, then don't. Nothing is forcing people to share their content.
DRM is saying you want to have your cake and eat it too. It's sort of like they're sharing content with you, but not really. You have to consume it the way they want to you to consume it. That's trying to control the experience, not the content, and I don't see any reason content creators have that right.
If they don't want to let the content loose on the world, then they don't have to.
