You didn't write the code for the bios, nor could you.

There's always a degree to which the manufacturer has to.

What about Coreboot/Libreboot?

Even with Coreboot on anything vaguely modern, there is a 'Management Engine' or 'Platform Security Processor' you can't practically control. On the better understood Intel versions, this is running a full MINIX 3 operating system and controls the network card in ways the BIOS and operating system root cannot monitor. It runs a significant amount of code; with hardware obfuscation that has not yet been broken.

You are right of course, but I consider that a hardware concern, not BIOS.
