I'm not defending AirBnB, because they totally enable and profit from scams as documented in the original article. But it is just the user expecting to get hotel services (rebooking and room swaps) from a non-hotel (whether genuine homestay or micro-hotel-entrepreneur).
AirBnB wont play down that expectation because again they profit more from it, but from the website and concept it is clear that you are dealing with random unprofessional strangers with a minimum of guarantees. Its kinda like the Uber contractor-vs-employee categorization for drivers.
AirBnB should definitely do a better job, but I maintain the risks are inherent in the business model, and you and the other users want the benefits of the risk (lower prices), without accepting the consequences of the risk.
