I did a work on DRM during my master degree. It's somewhat true, it's called Broadcast Encryption. They can stop your players ability to read new disks. They can't stop existing ones though, unless the disk requires online component or something.

DRM stands for Digital Rights Management, but I call it Digital Restrictions Management cause that's what it is from users point of view.

https://en.wikipedia.org/wiki/BD%2B

The one thing I'm not 100% certain on is if HDCP revocation list updates go through BD+ or if there's a separate mechanism for those updates. However, BD+ code gets to inspect your player software and modify it, which is sufficient capability to do updates, even if they don't use it for such.

I also don't know if they continue to release updated BD+ code or if they've given up on that.
