The "fix" for this with video was mandating a new "secure path* signal protocol which rendered all existing HDTVs and receivers and related equipment obsolete.

This is happening again right now with 4k for those who wonder. Yay.

Oh. And the OS would need to enforce the secure signal path thing at kernel level, with GPU drivers having to support this.

Pretty much a crazy amount of work to prevent piracy for everyone involved, except those who want their content "protected". And it still doesn't work. So all that effort was utterly wasted.

But yay, let's repeat it!

You pretty much just described all DRM. I don't see how this is different on any philosophical level.

stuff like intel SGX goes a long way to making something like this possible.
