As a guest from the UK when you go to do a search on Airbnb you always see the total fee due (it's been that way for the last three years @Ian39
When you go to book you see a breakdown including the airbnb fee, cleaning, local taxes etc.
what may have confused things for you is that some hosts opt to pay the Airbnb fee so you won't see it when you book (all they do is increase the day rate you pay to take into account they are paying this fee)
The amount Airbnb charges is actually less than similar STR platforms
in summary you will always have paid the Airbnb fee.
You can look for owners that allow you to book directly ie not on Airbnb or dimilar if you want to avoid the fee that short term rental platforms charge.
