On the one hand I can understand it. Default wireless settings amount to your router screaming "I AM HERE, YOU CONNECTIONLESS IDIOTS" down the whole street. Simply writing this information down that is constantly broadcasted by your device is not an inherently bad thing to do.
But yes, connecting all these hundreds of dots across multiple devices, systems and whatnot is where it gets terrifying. Just like HTTP, WLAN protocols have not been developed with security as a top priority. They are simply not made to protect from tech-surveillance companies. They are meant as utilities for everyone to share freely.
