They didn't even contact the FSF to discuss the matter. FSF wrote a white paper about this and stated that the GPL would not force them to release the public key. Also, does anyone really believe UEFI is not going to be compromised ? The entire thing ridiculous. It's a power grab, and a lot of leaders in the open sourced movement are going to come out of this looking like a pack of fools.
