Hi Zandra,
you are well informed! (How come?)
Actually I saw that change in my dashboard by coincidence about one or two weeks before they officially wrote an email (but I must have overseen that it's only for Italy). So I was kind of not amused finding it out by coincidence!
I checked the community center and googled, but couldn't find any discussions so I jumped on Cynthia's post as it was the first I saw after the feeling airbnb shifts its focus on guests.
I observed for the last season getting less guests on airbnb, meaning that another site is taking away shares from airbnb. I assume that the smart guys at airbnb are observing the same and trying to get their guests back and even getting more guests to book on airbnb because due to the incresase of airbnb hosts, the competition is thougher and more hosts have to "fight" for their share of the cake. Maybe my rant was too fast. Maybe it will benefit us hosts in the long run. After hosting 3 years, I had maybe 3 cancellations and none was with airbnb (if I remeber well) because, my observation is that airbnb guests tent to be younger and more spontaneous for "last minute" bookings, while on other platforms the older guests sometimes plan up to a year ahead and then change their mind...
Unfortunately all agents, not only airbnb, increase their commission on a yearly base, slowly and often secretavly.
