I believe there is actually a screen on the device, so people are actually watching porn on the public kiosk, as opposed to their own device which is connected to the kiosk via wifi.
Yes, there is a screen. I can verify people chilling at the kiosk while having youtube videos playing for hours. I have not seen people watching porn though...
Yup. Reading the (short) article one sees they still have wifi for personal devices. So, now can only abuse if have a phn, tablet, or laptop (or watch, all these form factors!)
