Wifi on club sites

All the non club sites I have been to have FREE WiFi throughout. The club still insists on charging for WiFi connection?? Free wi fi connection is the norm in retaurants, pubs, hotels, buses, trains and I understand even in some taxi cars. Why does the club still insists on charging?
