Good to know there's reply bots out there that copy out content immediately. I rarely run into edit conflicts (where someone reads before I add in another thing) but it happens, maybe this is why. Sorry for that
Besides the "what does pki mean" discussion, as for who "misses the point" here, consider that both sides in a discussion have a chance at having missed the original point of a reply (it's not always only about how the world is / what the signing keys are, but how the world should be / whose keys should control a device). But the previous post was already in such a tone that it really doesn't matter who's right, it's not a discussion worth having anymore
