I don’t think they “get mad.” Lots of people sync calendars. It doesn’t matter if your calendar is blocked because you got a booking on Booking dot com of if it’s blocked because you are doing remodeling.
It’s not reasonable to think that you will be booked 100% of the time when the number of hosts is growing faster than the number of guests. And when the next economic downturn happens there are going to be a lot of hosts in pain and blaming Airbnb for their dependency on Airbnb income. Airbnb is impersonal. If you do what they want you to do (instant booking, low/smart prices, flexible cancellation policies) they will put you as high in the ranking as they can, but there are limited spots at the top. It makes sense that they would rotate the results to give more people a chance to get bookings. It makes more sense from their point of view for 60% of the hosts to be 80% booked than for 40% to be 100% booked and the other 60% share the leftovers.
