Not my niche, but Talos II probably serves that niche well.

Its workstation class, aimed at $5000 computers on a completely open framework.

I'm not convinced that the AMD EPYC feature is malicious however. So I personally would still go with Threadripper or whatever.

ARM based platforms such as Allwinner and Rockchip CPUs which are free of these security measures. Though the performance is very poor in comparison, however over the next few years the situation might improve.

I'm mad at intel for what they did in the past, im mad at amd for what they are currently doing, which do you think will win out?

As Intel's Boot Guard is essentially the same feature, and not a thing of the past, my guess was neither of the two. I didn't try to be snarky, I'm really interested in alternatives.

I can't find anything on google about Intel boot guard meaning that plugging a cpu into a motherboard can bind that cpu to that motherboard such that putting it into another motherboard no longer works.
