Honestly, that sounds pretty fantastic. I've been using 3rd party tools/extensions to do this sort of thing in corporate and government environments for years, but having the attestation go all the way down to the hardware level is a big value-add, especially with so much ransomware/spyware/extortion/espionage going on these days.
Can someone please explain to me how the author might see this level of security as a bad thing?
News of Pluton and its security goals have been readily available since 2020 from reputable hardware sites like Anandtech, or directly from Microsoft themselves. There's nothing new or hidden or surprising about it unless you live to dream up Microsoft conspiracy theories.
Many other hardware manufacturers have similar security offerings including Intel and Apple. Microsoft is arguably late to the game here, given their only recent interest in PC hardware. OS integration isn't even new. Macs have been shipping with T1 and T2 chips for over five years. Has the sky fallen on that ecosystem?
