@Mary996 It is not that complicated. What Airbnb has done is charge hosts a low fee (3%) to list with them and flood the market with their listings, and thus capture a huge percentage of the market. In turn, it became a bonanza for those listing with them: low hosts fee/tons of customers - happy days. Over time many hosts are demanding more and insisting Airbnb do what they promise. The world is full of false promises, think of a used-car salesman.
Examples: the Host Guarantee and Customer Service for hosts, are just more bait in the hook. Both can't really be supported economically by charging hosts only 3%. Still, in my book, Airbnb is a great deal, especially if you look at them as a great booking service for only a lousy 3%.
And the money is not coming out of what the guest pays either, because they are keeping that smarting relatively low also - in the range of ~15% to guests.
In a nutshell: The day they really have to deliver on services hosts think they are entitled to is the day hosts will not be paying just 3%.
Btw, we are a friendly lot here and trying to help one another, including you, but hard to do when you continue to argue even with your own shadow.
