Unfortunately the same business types who demanded such a ridiculous self-own as an integrated CPU-level backdoor also pressured AMD into shipping the same thing. And we know less about the AMD PSP than we do about Intel ME.

ARM is no better, either, at least in practice. Their relatively friendly licensing terms would allow a vendor willing to make their own silicon in volume to ship a no-TrustZone, no-Secure-Boot SOC. However, nobody does this. In fact, moving to ARM has traditionally been used as an excuse to lock out third-party operating systems and unlicensed software. (Remember Windows RT tablets?)
