Airbnb is a business. And honestly their behavior is exactly what I would expect from them: dont admit any liability, offer words of consolement.

This isn't an isolated incident though.

Their whole business model pretty much is built on the fact that things like this will happen. A lot.

Given that they control the communication, the implied business model is that trustworthy people will be using the service.

If they truly expected these types of incidents to happen a lot, they would require more information from people (to be able to trace and hold visitors accountable) and have some sort of legalese to ensure that they would never be held liable.
