But so does a USB-connected security dongle. Does that make USB "complicit in enforcing DRM"?
TPMs are really just embedded Yubikeys. Unless your UEFI/BIOS "conspire" to supply them with boot measurements, and your OS in turn conspires with that to carry these measurements forward and provide them at the application layer, TPMs can't harm your freedom.
TPMs are a much more "freedom neutral" technology than people generally assume in these discussions.
The TPMs are already provided with boot and OS measurements for secure boot purpose which would allow DRM to confirm you use an approved OS kernel, so I guess the computer is already conspiring. And the conspiracy could be enforced by videos distributors in exchange for the privilege of having HD content.
It could, but why? They've come up with a solution that avoids having to place any trust in the OS at all, so why introduce additional complexity and fragility?
If they don't have a GPU that implements this then the decrypted material would be available to the OS, which is precisely what the streaming media platforms want to avoid.
It's because they don't trust the OS not to leak the decrypted bytes, but they could thanks to TPM (the OS would have to have a memory memory chunk not readable from admin/root etc). In this scenario the OS is part of the DRM.
Mandatory where? Most of the devices people are streaming video to these days aren't even PCs!
Macs haven't had TPMs for a while now (I think Apple never really used it and dropped it even before the Apple Silicon switch), but of course they have their proprietary equivalent.
Yes, but Windows isn't where the vast majority of people watch Netflix, so I don't see the incentive for media DRMs suddenly also making TPMs mandatory.
