To assume that UEFI with some magic numbers is a security provider with
current hardware is only a day dream .
Consider stolen security signing keys and other by-passing mechanisms .
For me , I think , over time there will exist free , but really free
operating systems which they are not enslaved themselves to some companies
, and hardware ( mainly main boards ) which will not require such enslaving
. Then , to do task is just plainly to switch to such hardware and software
Personally , I will never want to live under a restriction tried to be
enforced by a company and blindly accepted by its followers . I think I am
not the only one in the world .
Thank you very much .
