Because maybe that hasn't been the case for the people still using it? It certainly hasn't for me, and I've seen other comments in this very thread saying as much[1].
Hasn't been a problem for me. I apply common sense and do the absolute minimum, usually starting the dishwasher. They can ask me to do whatever they want but it has no teeth. I've never seen one of our hosts complain in a review either.
Which also shows you how little oversight they have - I guarantee that there are a sizeable number of places that are not inspected after each stay, let alone clean.
This would be so obvious I have trouble seeing how you might believe it. The bed wouldn't be made, the dishes wouldn't be cleaned, the items of the house wouldn't be put back.
It is also trivial to look at a bed and see if the sheets have been cleaned even if the bed was made -- hair shows up easily if not other stains.
