The author is correct in that media DRM is tied to GPU vendors on the field right now.
But hardware backed DRM can be so much more invasive beyond that. I have no doubts the long term goal of MS is to have a Windows version of Play Integrity.[0] So total control over everything that happens on your device. Just to give an example of what could happen if this becomes reality: https://en.m.wikipedia.org/wiki/Web_Environment_Integrity
This tech extended to browsers could easily mean that sites could refuse to serve you if your machine is running any bigcorp unapproved software. An easy example of that would be adblockers.
Unless we get lucky with secure world compromises like the Tegra X1 bootrom exploit[1] or get real good at passing legistlation that forces companies to give you all the private keys to your own machine, the future for personal computing is looking grim.
