@simplycorbett Yes that is the case, but you are free to remove it from the menubar if you wanted to.
This policy will prevent that you can do that if enforced.
@simplycorbett I removed it, space on my 13-inch MacBook is limited and I rather spent it on more pressing things.
A policy to prevent automatic connecting to unknown WiFi networks is, for me, sensible, controlling the Wifi indicator is not.
