If an ad can be rendered on a page or if it uses audio it can be blocked. We have it easy right now with how trivial it has been to block ads, but we could face off against rendering and wiping them in real time if we need to.

Not really. Modern DRM uses Intel ME / AMD / ARM equivalent. These execute code the OS doesn’t have privilege to access.

Oh really, that's news to me. I thought one could always read the video frames one at a time.

Nope, it gets access to its own framebuffer that’s composited in the GPU. OS sees a black viewport, and only a black viewport.

The comms is encrypted on the bus using strong cryptography, so you can’t sniff it.

All these software blobs are signed and encrypted, you can’t replace it without the signing key.
