The "Recall can't record DRMed video content" thing is because DRMed video content is entirely invisible to the OS. The OS passes the encrypted content to your GPU and tells it where to draw it, and the GPU decrypts it and displays it there. It's not a policy decision on the Recall side, it's just how computers work.
@mjg59 Thank you for explaining that. Now it makes more sense.
@mjg59 Interesting. So 'recall' still does the screen capture but the parts that are DRM'd just aren't visible?
@mjg59 It is a hardware design decision that tells you where their priorities lie and who they are willing to protect.
