@georgia Oh my god.
The VHDL source code of many IC's in your PC, including Intel CPU, but not only, count in several hundred million lines of code.
IME is just an official backdoor, but they are so many others. Every key element is backdoored, like random number generator, ethernet controller, the south and north bridges, etc..
The source code of all these IC's is larger than your debain's OS source code and you think they just inserted the well known IME ?
Same for the BIOS / EFI software.
