It probably would have to be an isolated environment to run in. Something like the Secure VM efforts adopted for desktops, perhaps with a small trusted hypervisor instead of CPU vendor extensions. Anything else I can think of starts to restrain what software you can run on your machine, or becomes highly invasive in ways similar to Anti-Cheats on Windows, both of which would be rejected by the general Linux community. (Through, it's not like anyone was asking Microsoft either before implementing anti-cheat and trampling on system integrity, at least until Microsoft started requiring signed drivers)

However, given that a generic blackbox implementation enables DRM and binary encryption there will probably still be opposition. It gets particularly nasty if it's given access to something like a full TPM to unlock application data in the same way a TPM can unlock an encrypted drive for your OS. That would make it the penultimate closed source application, which is really anti-ethical to a number of communities. (open source, modding, game/app preservation...)
