Boycotton all recent x86 CPUs is probably not reasonable for most people. More actionable is to make sure you control the software (most importantly, the OS) that runs on those CPUs so that their user-hostile features are not used for DRM.

You're right, not for most people. But we aren't most people here, and can stick with older AMD for desktops, as well as should be heavily investigating the alternatives like RISC-V (and also the "true" Linux, non-Android smartphone alternatives for somewhat related reasons).
