They need DRM thing ASAP. Next step would be to auto-fail every device without hardware TPM module (including Win11 with bypassed TPM requirement). "This software wont run on this PC" "this movie won't play" etc
I'm aware of zero DRMs that use TPM, despite being a DRM boogeyman for over a decade. Meanwhile there are plenty of actual DRMs that use HDCP and SGX and there's not a peep about those technologies. Moreover the war on DRM is basically over, for both sides. Smart TVs and streaming boxes (eg. fire TV stick) are ubiquitous enough that basically everyone uses those devices for playback, rather than bothering with the hassle of plugging in their laptop and dealing with the fickle DRM experience on PCs. For the tiny minority that wants to watch on their PCs, 4K rips are ubiquitous enough that nobody bothers watching the official DRM encumbered version.
