Even before AirBnB this has been the case. You take out the trash and start the dishes in the dishwasher.  Sometimes strip the bed. The cleaning fee is then for the actual cleaning of floors and bathrooms etc.

The standard has changed/fluctuated maybe over time but this has been common for ski condo and wood cabins for instance for decades

Personally I tidy up any rental out of respect it is not my property. This includes hotels and car rentals... I don't go nuts but I at least toss things in the garbage etc.

This sounds like common sense. It has no place in this realm.
