I guess this implies high quality WebRips for years to come, because blocking Intel Laptops isn’t feasible for any streaming service. And from what I heard, control over SGX would let you extract the WideWine etc. key store without!!! the OS knowing about it. So this is like a secret debug access starting at OS&TPM level.

Widevine L1 has never been used on Windows machines anyways. PlayReady SL3000 works on Windows machines, but that’s broken already anyways.
