Although I could be wrong, I think the owner of the casino also owns almost all of the Maho property, so I wouldn't personally have a problem with it, as you're still patronizing one of his tenants. ...and in general, I don't feel too sorry for someone who owns a casino. I don't view it as the same as using wifi from a restaurant that you don't buy a drink from, although I guess the analogy can certainly be made.
