You are not alone. The CoreBoot (https://www.coreboot.org/ https://www.coreboot.org/) project is maintained by programmers who would agree with you. The main problem with opensource BIOS is the need to understand several proprietary interfaces. As for the CPU, have a look at the RISC-V project (https://en.wikipedia.org/wiki/RISC-V https://en.wikipedia.org/wiki/RISC-V). I have seen links to implementations but I can't find them at the moment. You might want to consider systems built using ARM processors instead of Intel. There are several proprietary backdoors in Intel CPUs.
