AIR BnB takes some more heat

I wrote about Air BnB a few weeks back, and it seems city's have a different idea about these un-taxed hotel rooms.  After all something can rent an apartment for a couple grand a month and they offer it as a BnB for a boatload a night!  What if the apartment is under rent control?  There is a concern that short term rentals will hurt affordable housing for the permanent residents.
