No, I wouldn't expect a friend to make restitution at all - unless, of course, my friend had done this sort of thing millions of times, knew I was likely subjecting myself to the risk of eviction (probably completely inadvertently), and didn't bother to say a damn thing to me.
If, instead of warning me about the stupid risk I was taking, my friend highlighted things designed to make my behavior seem risk-free (like, say, a million-dollar property damage guarantee), well, then I might feel a little differently. If my friend had built a multi-billion-dollar business off of the risky behavior of me and others like me, then I know I would feel differently.
But this is a moot point, because friends don't let their friends engage in risky behavior without at least making them aware of those risks. Someone that does that isn't your friend at all.
If I were to consider renting my place on AirBnB, I would consider the people staying here to be my guests, not ABnB's. While I believe there is some concern with how the company represents themselves, the fact remains that it's his apartment he chose to rent out. Illegally, I might add.
If you rented a room to someone referred by a friend, and that guest trashed your place... would you expect your friend to make restitution? (Personally, I would downgrade my trust in that friend's opinion, but I don't think I would hold them liable...)
