Every Intel CPU since 2006 and every AMD CPU since 2013 has this stuff. If you care about this possible solutions are: buy pre-2006/pre-2013 hardware; go through some procedure to remove the ME[1]; forget x86 entirely (ARM?)

Yes, all modern AMD processors have this. But Intel processors have an equivalent ""feature"", called the Intel Management Engine (ME). So take you pick really.

Intel already has Intel ME.

Intel does the exact same thing they just call it "Trusted Execution Technology" https://en.wikipedia.org/wiki/Trusted_execution_environment#...
