How hard is it to make firmware, CPU's and BiOS etc.

I am personally of the opinion we cannot trust corporations to look after our best interests as a species. They will look after a handful of people to excess, but abuse the rest of the population for profit.

That said, is there any path forward for open source/free:

* CPUs * Motherboard BIOS/CMOS * Firmware in proprietary devices

Thoughts? Am I the only one getting a bit peeved with wealthy corps trampling on the tragedy of the commons and us as a species?
