I think there’s a difference between what people think they’re aiming at and what they actually aim at.

Media DRM makes it harder for the person who can already legally access it to use it or share it in an unapproved manner. Or maybe to avoid ads, but that’s pretty rare.

So DRMing a media file or stream has approximately no effect on the ability of a non-paying customer to get pirate it, because anyone searching for a pirated copy can find a DRM-free version anyway.
