The practice is questionable at best, but it's a good reminder about that everying sent with radio waves can be picked up by others even if they were not the intended recipients and no matter if you want them to or not. It's pretty much like leaving the front door unlocked -- it would be unethical to use it to go inside and steal your stuff but we still need to lock the door if we want to reduce the chance of someone stealing your stuff. Tips for avoiding this: - Change SSID at least once per year. - If your router support multiple SSID's, turn the current one off and use the next one in the settings instead -- it will usually result in the MAC address being changed as well. - Do the above whenever you move the router from one location to another.
