I agree, and I don't know why anyone would disagree sufficiently strongly to downvote your comment for suggesting that. Microsoft being directly in control over what can boot by default on PCs was and still is a blatant conflict of interest, and transitioning that decisionmaking to an independent body with input/control from more than just Microsoft would alleviate that considerably.

Yup, we did it with SSL a long time ago...

Possibly better not under US control? Though I kind of reckon it'd have to be some inter-governmental thing rather than "pick a better gov". ;)

SSL isn't under government control, the same thing could be applied for secure boot.
