Honestly I think those requirements are perfectly reasonable for the originally intended purpose of the site, which is people renting out their personal homes. I have stayed in several Airbnbs that had the owner's clothes in the closet and pictures of their kids on the wall, and in those situations, it just seems rude to leave dirty dishes in the sink. These places aren't hotels.

I agree that doing laundry is a bit onerous in clearly dedicated rentals, but in my experience those tend to have fewer requirements and tend to not care if you miss a couple steps unless you trash the place.
