@Susan1188 Like @Mike-And-Jane0 says above, some absurd things have already changed, or promised to, and how things will really work out is yet to be determined.
However, one thing is for sure, the home-sharing model surely will be getting more complicated and thus the Airbnb involvement even more necessary. Meaning things will be decided more through the mentality and capability (or lack of) of their CS Department. Yuk.
I have been a proponent of keeping the model as simple as possible - Airbnb is a booking agent, end of story; for that they only charge 3%, thank you very much. Airbnb need not even be involved in any 'guarantees' for example, for anything; so making it work falls on me and the less Airbnb is involved the less they facilitate hustling by guests which is sure to happen if given the chance and then surely the only-3%-host fee will continue to happen.
I see hosts, guests and Airbnb prone to behave about the same having the same human nature; considering all three come from the same human gene pool no wonder.
