I'm not even sure it even means "work harder, not smarder and wach yor seplling." In my experience it's more of a shibboleth to the new masters to let them know they're down with creating a top-down organization where information flows only one way.

Were I to have crafted this post, it would have included things like

"We ask our employees, customers and investors time to prove ourselves to you again as we re-commit to listening to our stake-holders and ensure our organization is properly re-positioned to execute our continued plans to deliver the best possible service..."

But instead it comes across as "someone read an article about Amazon's two-pizza team rule and we figured there were worse things to try."
