No, this appears to be a HN urban legend. It's always asked in these threads and the closest thing that anyone has been able to provide is one person asking one time on the samsung forums why there tv was connected to the neighbour's wifi (openly in the TV's own menu). So either there's a giant conspiracy which literally nobody else in the world has noticed or attempted to reproduce, or her kids/neighbour/whoever just connected it to the first network that'd work.
