so what you're saying is that without TEE, Netflix would shut down? come on. Netflix would clearly keep operating with or without DRM, all TEE does is make it harder for the user to access their legitimate (non-Netflix) content in anything but the most approved way. it entrenches mainstream operating systems and makes it harder to use FOSS. sure, I'll concede that Netflix is not the most damaging to user freedom, but that's not what OP is about. nobody would give a shit about this vulnerability if it was just Netflix, because Netflix is broken against hardcore attackers anyways. TEE proponents want to expand its use to more user-hostile applications. that's my concern.

hardware encryption is arguably a better use of TEE, but as far as I know, no actual implementations use SGX for that purpose. the TPM is used, but it's not fast enough for actual encryption. the OS loads the keys from the TPM and does the encryption in regular software.
