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.
These guys do interesting work but note that it's all on an old obscure Atom processor. I guess they can't hack any Core processors.
