> In my case, the audio devices menu on Mac/iOS displays nearby AirPlay targets, including those not on the LAN. My neighbors got their misconfigured so it always pollutes my menus with no way to disable this even though I never use AirPlay and don't have any compatible hardware (nor intend to get any). Every time there's a risk of misclicking and accidentally broadcasting a meeting's audio or (if they have auth enabled) annoying the neighbor by waking up their Apple TV (or taking over whatever they've been watching)

"Accidentally" broadcasting a few times is probably all you need to do to get them to fix their stuff... They probably don't even know.
