Bucking a “Best Practice”

Why avoiding the “Change port 1433 Best Practice” might be the “Better Practice” to follow

A lot of quality resources in the DBA community (e.g. MS, Jonathan Kehayias, Green SQL, etc.) state that changing a default instance’s port to something other than 1433 is a security “Best Practice.”  While I may agree that you want to avoid using port 1433, I contend there are better ways to go about it.
