I saw a thread on here on how intel CPUs are backdoore and it was cute seeing someone ask "so are AMD cpus fine?" In this post I'll go over the full extent of backdooring (protip: EVERYTHING)
1: CPU level
Since 2007 it's been public knowledge intel has put 3g modems on die that can operate without power to spy on iran, complete control over the system. AMD has done the same (released by wikileaks, publicly released as Intel AMT/vPro or whatever AMD calls their equivalent)
Since 2012 they have put ON-DIE-MICROPHONES that operate without power "so you can turn on your computer with voice commands" (released in mainstream media)
With these facts in mind it's safe to assume at least 1 chip on every piece of hardware on your PC (mainly CPU, Mobo, and Hard drive) have network connectivity, a microphone, and a plugged into a data mining network. With these facts in hand the rest of the backdoors don't matter because you're compromised no matter what. Also note these are forced by the government, companies have no choice.
2: Software level
everything since XP has an unknown software backdoor of unknown size and capability. "muh w10 privacy hacks" are a joke.
Sources?
fuck you this has been public knowledge for years
