For one, it's against every rental agreement I've ever signed (no subletting clause). Another reason people don't like it is due to the party people who frequently rent these, the extra parking spaces being used, people moving around at all hours, people not caring about the space because they don't own it, etc. Basically all the things which are incentivized in normal multi-month rental contracts which are not present in Airbnb contracts. People who live in an apartment building don't want a hotel room next to them.

> Why should not be able to advertise/rent your apartment on Airbnb?

It's already been illegal to rent out a whole apartment for less than 30 days. The new law just extends that to advertising the unit.

Basically, the law now prevents you from advertising a service that was already illegal.

> Why should not be able to advertise/rent your apartment on Airbnb?

Why should you follow any laws ? after all, you can do as you please, no one forces you to follow the law. And no one's going to feel sorry for you when you get caught.

There is a lot of stuff you can't do to your own house/apartment without violating some rule or law. This is old. Airbnb can be disruptive in many negative ways and not every community feels that the trade-offs of letting them do as they please are worth it.
