I agree; I don't think it's right either. To take your hotel analogy, I agree it's not right for customers to make copies of room keys. But if it were as easy to copy a hotel room key as it is to copy a wifi password, the hotel would not be in a position to describe those keys as adequate security. Though the analogy is poor because a hotel room is intended to be a private and secure area where I can store valuable item, whereas wifi access is more like the soda dispenser at an American restaurant—other customers are equally inconvenienced whether you paid or not.
