If you can't trust the hardware to do exactly what it's told by a trusted entity that isn't the current hardware owner, then you can't trust any DRM scheme to work.
And since practically every known DRM scheme that people care about so far has been cracked, there's no reason to believe it will succeed in the future. Everything we know about physics says you can't give somebody a box with both the content and the key and stop them from extracting enough information about the content to recreate it. There's always some way to find out what's in there.
And besides, how would you be able to trust the manufacturing process in the first place? And identification of the hardware? On a global scale?
As long as the entire processor and RAM is untrusted, you've got no chance, and it will stay that way forever.
Also, it doesn't really count as "open source" if the user has no ability to modify how it works on his own devices.
