I read in Ithappens:

So, changed a little on the old good TP-Link settings: called the network "Free Wi-Fi", removed the password from it and physically disconnected the external cable. Literally in 15 minutes recorded seven neighbors - lovers of the hallway.

First, this is probably not the fans of the hoodie, but the devices that remembered the network with this name elsewhere and connected it when it appeared in access.
Second, I don’t quite understand this attitude. Opening for those who want free access is quite a common good thing (well, if you are not afraid of any problems with false reports of terrorist attacks or other abominations). The name of the network indicates that it is not an accidentally forgotten password, but a conscious permission to use. And a deliberate joke with a free-way without internet is about like going to a bus stop with the inscription "free trip", and then taking the "hullers" into some dust - let them go on foot, go, hullers want.
