I feel the same way about digital signatures, companies want people to trust their signatures, but are they going to share the signing keys and let others in on the fun? No. Everyone just goes around saying its their keys, their identities, you can't let other people use them, what if someone abused them. As if there was more value in having a trusted identity than in the value of the money I could make from the rootkit I would sneak into Debian.
