I think the issue is that Airbnb claimed and advertised they would begin offering true pricing that included all fees displayed upfront so you could compare all the bookings against each other in the search engine and not buried in the terms and conditions:

It's insanity to have to search through each listing and add random fees to compare the prices of different listings against each other. I don't think the OP disputes that this appears in the terms and conditions.
