I wish they'd gotten some answers for the Viceroy situation, which is the main sketchy part of this endeavor. Beyond that it seems like a set of real vulns with pretty real impact hindered for the HN crowd by an overly glitzy PR push. The ToB blog post is what should have come out concurrently to satisfy the overly cynical HN crowd - maybe good notes for CTS for next time. It's ironic that the overall reaction here was so jaded when people are up in arms about Intel ME every time it's so much as mentioned.
Intel has been cleaning up as of late, going all the way back to the earliest Core processors with patches. That's some Microsoft level of support, probably because there are old enterprise deployments, and it speaks to how Intel is different from AMD in tenor.
