Surely spoofing the user agent is unobjectionable at worst, and spoofing the MAC address perhaps only mildly discouraged? I can't imagine its actually being illegal (but, then again, see http://en.wikipedia.org/wiki/Legality_of_piggybacking for unexpected illegalities).
Well, it depends what the hotel policy is. If it's "free wifi for Apple devices" then there's some kind of fraud happening.
The fact that the hotel is incompetent in preventing that fraud by relying on UserAgent seems less important than intent of user when changing UA string.
I'm not sure that I agree with that interpretation --if you stand on the street and say "free hugs for Georges", and I say "I'm a George", has fraud occurred? I guess that I mean --is any misrepresentation, even in the absence of a contract, a (legal) fraud?
