I don't think it's the same situation as somebody reselling goods you've sold wholesale. As other posters mention, running a commercial operation from a residential apartment brings with it a number of insurance concerns for the landlord, safety and security concerns for other tenants (which would also be the landlord's concern), and no doubt a host of other liability issues which I'm ignorant of because I'm not an NYC landlord. If you were a landlord who was an AirBnB fan, you could certainly choose to not include clauses that specifically forbade this sort of activity. This guy chose to lease somebody else's property and then go ahead and use it in a manner that was expressly forbidden by his lease agreement to line his own pockets. I have zero sympathy for him. He got slapped down for misusing somebody else's property and rightly so.
