It just shows that someone is writing something from their personal perspective and thinks the rest of the world should conform to their view points. Also, it really sounds like a recent cloud "convert" trying to make hay as a thought leader (which is a phrase that makes me want to hurl), all the while revealing their ignorance as not fully understand the topic at hand. In other words, typical blogosphere crap (even though this isn't really a blog, just a syndrome).
The users & keys part is actually just a tiny part of it.
