To be clearer regarding my questions:

- What happened to Project X (supposedly coreboot++ for latest AMD CPUs)? It seems dead, despite being more reported on than Oxide's attempts in working with AMD (to achieve the same outcomes, presumably - what's the difference?). Loads of well meaning people have approached this with virtue, innocence and skills; perhaps another approach is needed that fully respects the dynamic between the user, the chip manufacturers and the governments and banks they're in debt to.

- Does Oxide attempt to sandbox, completely remove or 'verify as benign' aspects like the PSP? For example, if someone could verify that the PSP cannot possibly be affected over the network, then peace of mind could be more affordable regarding things like supply chain attacks and bad actors with AMD/Intel/Apple management engine secrets.

Not referring to software lock-in, just hardware. And it isn't very nefarious like other hardware lock-in (serialization, see Rossmann Group). Just hardware on the rack-level: replacing oxide gear & upgrading oxide gear (not sure about repair, that could be easy). And if the offering were of a less blobby architecture, then many of us would be happy to pay a bit more for the hardware as a system. However, if the hardware platform is FOSS, then it won't be unnecessarily difficult to mix and match and integrate the Oxide gear with other DC-class gear.
