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.

Are you sure Widevine uses the attestation functionalities of a TPM on Windows?

I thought Widevine on computers (whether Windows, macOS or Linux) is always L3, i.e. software only, and L1 needs a TEE on Android or an embedded OS such as on a set top box or streaming dongle.
