I see a lot of words in your post, but for the life of me, I can't figure out what part of the linked story you feel is "mud slinging", nor what "langauge" or "behaviour" you're so disappointed about? AFAIK docker has had a crappy security story from the start, by design. Perhaps Docker is now, or proceeding to, leverage more of LXC/namespaces for "proper" security -- but the argument against a monolithic daemon makes perfect sense.

Security and convenience are always at odds: I don't see it as a problem that tools lean one way or the other: It does make me a bit worried if they lean one way or the other by accident -- which is what you seem to imply with your comment. I take it you're trying to "defend" docker -- but I don't know against what, nor do I understand your arguments.

Perhaps you could take a deep breath, and try again? I'm sure you really do have something to say on the matter, that is worth reading.
