DRM does not prevent copying. Everything that is broadcast or streamed is copiable. DRM has never worked.

Yeah I don't understand why it's not clear for everyone now that the only people benefiting from DRM are DRM makers. It never actually protected anything. The most outrageous example is HDCP, for which I believe one of the master key has been leaked and it's publically known (so the protection it might have offered is void), but customers still pay the HDCP tax to Intel on every device that must support it to work with other devices...

  >but customers still pay the HDCP tax to Intel on every device that must support it to work with other devices... Please do some critical thinking. There have been 3 new versions of HDCP since that leak and they have all broken backwards compatiblity. Do you think they still use that leaked key? Or do you think as they have improved the security of HDCP they have replaced the key? If you went and looked at the security of Linux from over 10 years ago you would find some bad security vulnerabilities which have now been since patched. Similarly the security of HDCP is getting better over time and newer content is requiring the higher security that is available.

    Breaking backward compatibility would be another issue if devices cannot be upgraded, some kind of planned obsolescence where you need to throw away your perfectly working device for no good reasons. How does that work in practice though? Does it mean I cannot read recent blu-rays with older blu-ray players with the old key?

      >Does it mean I cannot read recent blu-rays with older blu-ray players with the old key? Yes, newer blurays may require a new player or a system update for your player in order to play if they require a newer security baseline than what you have. >planned obsolescence Intel did not plan for older HDCP to be broken.

        > Intel did not plan for older HDCP to be broken. What's the maximum time a DRM system worked before being completely broken? 2 years? 3 years? It'd be surprising that they did not anticipate that. But then again, I'm not sure why they would really care, they don't really make movies as far as I know.

>DRM does not prevent copying Are you trying to be pedantic? Technically the MMU prevents the copying. That is just an implementation detail. To content creators the distinction isn't important. >DRM has never worked. The barriers have seriously increased over time. Now you have to dump or buy a L1 key to decrypt content. Devices store the key securely which means that you either need to find a hardware vulnerability to leak the key or have a man on the inside to steal keyboxes. If you get caught your key / device will get blacklisted. With each year the price to break the DRM will increase.
