Earlier this year, we noted that a bunch of cities were looking to make Airbnb liable for residents in those cities using the platform without following certain city rules. As we noted at the time, this seemed to pretty clearly violate Section 230 of the CDA, which says that platforms cannot be liable for the actions of their users. San Francisco went ahead with such a law anyway, even though it tried to rework it at the last minute to deal with Airbnb’s points on why it was illegal. The case ended up in court either way — and unfortunately, the initial ruling has sided with San Francisco over Airbnb.
