Earlier quoted context omitted.
How is this different from trying a door handle to see if it's open.
In this case the “door handle” is marked with “pull to access the internet”, and he is pulling on it. The handle is supposed to have a mechanism to demand payment before opening but in this case it failed and opened right away. Not saying this is ethical (although selling WiFi for 12$ per hour isn’t either) but I wouldn’t go as far as calling this an attack.
Care to elaborate on this? WiFi on a plane isn’t any kind of thing people are dependent on to survive and satellites are pretty expensive. Airplane WiFi is entirely a luxury good.
Do you feel that charging $12 to watch a movie in a theatre is unethical as well? How about $150k for a Porsche?
