Researchers discover potentially catastrophic exploit present in AMD chips for decades
(www.engadget.com)
This is a most excellent place for technology news and articles.
It used to be a major pro-AMD reason for me too, but it's become irrelevant since pluton. Weird thing is, pluton was announced with much fanfare for Ryzen 6000, but I've not heard about it since.
Edit: I just read up on this topic again and found out that both purism and system76 disable the Intel ME in all their products (don't know if all of it is disabled, since it normally controls a lot of necessary components)
Edit 2: they can either remove most of its code from the flash, or use a disabling system that Intel had literally developed for the NSA.
