Some of us knew this 30 years ago

Why no service at all? DRM free services exist. The general trend is for DRM to die out. Music, gaming and e-book publishing industries move away from DRM. My point was the logic that any publisher and distributor should evaluate. I.e. publishers and distributors who use DRM reduce usability for their users. They increase it if they decide to drop it. Improved usability reduces piracy (as others pointed out, the better the service is, less likely some pople would pirate the content). And it doesn't affect those who would pirate either way (DRM or not). So, why don't publishers stop using DRM then? Surely not because they care about good services, and not because they worry about piracy.

Combine it with the fact that DRM is an unethical preemptive policing prone for privacy and security risks and it's easy to see that DRM has no useful and legit applications at all. All its applications are anti-user and nefarious ones.
