TPM isn’t about security, it’s about DRM

[etna_ramequin]

I’ve seen many widely deployed applications of TPM for security, never for DRM.

You've never used Widevine? If you ever tried to use a streaming website, you almost certainly did.

EDIT: To clarify, Widevine doesn't actually use the TPM, but Widevine L2 uses a TEE for key exchange and decryption, which are all things that modern TPMs support. The use a crypto coprocessor for key exchange and decryption is widely used.

DRM like full disk encryption, passkeys, etc. What DRM actually uses TPM? Pretty sure wildvine or any other common DRM tech use it to wrap the encryption of the stream. Why would it need?

No, TPM can be about both – and more.

In theory, yes. In practice, TCBs are so big, that DRM solutions based on it are nearly meaningless for general purpose computers.
