I wouldn’t want consumers to downgrade their systems and exploit already-patched vulnerabilities in order to circumvent DRM.
One could argue that DRM is evil and wrong, too. But then again, it enables subscriptions and renting and there’s arguably a market for both.
But I think this only works to an extent as, if you want your DRM not be trivially circumventable, it will be a cross-cutting concern and not easily restricted to a module.
E.g., the most secure TPM is useless if the OS simply ignores any responses and shows the movie anyway.
What you could do is to close off the whole media path: The OS only sees the encrypted media, which it sends to some combined TPM/decoding hardware, which more or less sends it directly to the screen. I believe to some extent this is what is done in practice.
You could technically see the TPM/graphics card/screen assembly as a "module" and can keep the OS separate of it - but this risks your "module" becoming so essentiall that it'll be unclear what is the dog and what is the tail.
In fact, we can already see things like unskippable commercials, apps with dark patterns and deliberate anti-features, smart TVs that suddenly gain banner ads, and political conflicts being played out in app stores.
All of that stuff is only possible because consumer devices are locked down and answer first to the vendor, then to the user.
You can say that all if this is an exciting new market that unlocks enormous amounts of innovation - I just don't think this is the kind of innovation that we should want.
However I think there is absolutely a general trend in the industry to see downgrades as a risk that must be protected against.
