https://www.reddit.com/r/Android/comments/8cb99a/android_verified_boot_remote_attestation/dxfnt4i/ … Good luck with that "unbreakable" DRM. How exactly do you stop someone from recording the screen? Widevine already provided hardware-enforced DRM without needing general purpose remote attestation usable for non-DRM purposes and other operating systems.
That's why devices with hardware attestation are actively harmful. Once they're near-universal, support for devices without it can be dropped.

Support for hardware attestation is universal across iPhones, Android phones, Chromebooks and most business laptops (TPM). However, until Android 8.0+, there was only proper attestation support for DRM. Android 8.0+ provides a general purpose feature and it supports other OSes.

We've spent months working on making the attestation feature usable for users to verify devices locally and now to pair devices with an account on our service so their integrity can be automatically monitored on a schedule. Not sure how exactly you think it's harmful to do that.

It works for both the stock OS and CopperheadOS. If there were other aftermarket operating systems that were fully signed with proper block-based updates and verified boot, they could also be added to our Auditor app and service. Users can built it to check for their key too.
