Why wouldn’t you buy a Ryzen because some epyc chips get locked?

I can't support AMD as a company as long as they are doing that on any of their products.

Currently using an Ryzen at the moment, my next CPU is likely to be a used Xeon because of AMD's PSP nonsense, which has reached a new low with the EPYC CPU 'bricking'.

On the Intel chips the ME security has been cracked completely so in theory someone could write an open source ME firmware replacement, although this might require a hardware mod to bypass the signature checks.

So what kind of CPUs do you buy, with both Intel and AMD out of the game?

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.

This seems more like a reason to avoid Dell than AMD.

I've always avoided dell, AMD should be avoided for giving Dell a chip API that let dell do what they did.
