It's not quite clear what point you're trying to make here. This is a lot of text, and it's clear you intended to contribute to the discussion: can you clarify what you sought to contribute?
Not the poster you're replying to, but what I read it as was: many employers posts lists like this, but they are not necessarily "clear boundaries", because often they don't mean what you think the plain-English bullet point would mean. The most common one is that "safety is our #1 priority" type rules often have a very nuanced interpretation, with an unwritten subtext of, "but don't cause trouble by pointing out safety problems".
On the other hand, if the goal is to cover your ass, then broad rules that are somewhat ignored at management's discretion may be a feature rather than a bug.
Someone could use the article as a guide for what not to do in an attempt to increase job security. I was trying to illustrate that may not be always applicable. Some discretion gauging your work environment trumps the article.
(And it was a cathartic counterpoint. This guy sounds like a great employer.)
