They can't do the same with NYC because the entire premise of AirBnB is illegal in NYC unless specific conditions are met. Since 72% of listings are technically illegal, there is no way they would shed 72% of listings just to make the remaining 28% tax compliant. This is why many view them negatively -- they blatantly facilitate illegal transactions. The fact that they are doing tax deals with other cities only underscores that they clearly know their users are violating NYC law.
