No, stop this line of thought. Won't work. If one option is "Secure Boot" and another is something like that we lose. We have to try like heck to influence what phrases the average tech journalist ends up using.
"Vendor Locked" for "Secure Boot" is a phrase we would win on and it just happens to be a lot more accurage. After all it isn't likely to be all that secure but it will tend to act as a way to lock any hardware with the Windows 8 logo to Microsoft.
And we want a nice suit friendly phrase for us to all get behind for the open option. "Vendor Neutral" perhaps? Or just "Unlocked" and an opened padlock logo? Or springboard off the phone/tablet wars and use "jailbroken" with an open cell door. If phone makers are seeing the wisdom as pitching it as a feature it is a pretty good bet motherboard makers would.
Or if the product includes the ability to install our own keys we get even better options to win the idea war. Imagine a logo of a closed lock with a key in the lock and another dangling on a ring like a brand new padlock. And something like "User keyable" under it. Carries all the warm fuzzies of security (such as it actually is) while also giving that user empowerment vibe.
But I'll say it again. If we can't raise enough of a ruckus to get seamless keying built in as an expected feature we are going to eventually lose. What I'm talking about here is that a new machine boots with NO keys. You pop in the Windows 8 media and pick "Install a new OS" from the BIOS and it grabs a keyring off the install media from a standardized location, adds (not replaces) those keys to it's store and boots the media. Later you stick in Fedora and do the same thing. OR if no keys are on the media you get a scary warning about it and are offered the option to install an 'insecure' legacy operating system.
