That's just the HAP bit. The ME is limited but NOT disabled, and the
remaining stubs are still hackable .
Neither the ME or the PSP can ever be removed from their respective
systems. They can both be limited to some extent, but to call either of
them "disabled" is rather far from the truth.
This all being said, it's great to see a light being shed on the ME. It
shows just how dangerous an embedded, mandatory core with signed
firmware can be.
