The answer you're looking for is here: https://plus.google.com/+IanHickson/posts/iPmatxBYuj2 (no, seriously)

The answer in link is already answered years ago. Publisher cannot stop piracy because it cannot control user device, because user has full access to device. So the only solution to problem is to gain full control over user device, which is impossible, because user device is in hands of user.

Except it's not impossible. Look at iphone and increasingly android. The device is locked down so hard that even the user doesn't have root access. Gaining root can be seen as a negative, borderline criminal thing and you lose warranty and repair service from the manufacturer. You also lose the ability to use some apps (Android pay, snapchat, etc.) just because you have root access.

The only ones with true root access are Apple and Samsung/Google.

More and more it feels like we are reinventing the mainframe/minicomp era.

That argument hasn't made them change their mind on copyprotection for decades. Why now?

DRM pushes people towards legit outlets, often because the pirate version is of lower quality, bound with malware, or arrives later than the legit version does. Stop seeing DRM as an unbreakable lock and start seeing it as a cost optimisation problem and you'll understand.q

DRM pushes people against legit outlets, often because legit version is of lower quality (e.g. HDCP), bound with malware (e.g. Sony rootkit), or arrives later or even never, because market too low to care about (e.g. Linux/BSD, or local markets of non-English speaking countries), that the pirated version does.

What malware? Piracy is a better product because it doesn't have DRM.
