As others have explained, the title Airbnb comes from the original concept that you could rent out an airbed on the floor of your living room. It's rather silly to take it so literally. Airbnb has evolved quite a bit since then and now you can book anything from a teepee to a castle. Every listing is different and therefore the amenities are different. Every location is different (here in London it is very rare for a host to offer breakfast and like many places, you need a food license, inspections etc. to offer catering to customers).
It is the guest's responsibility to read the listing and select the one that suits their needs. Guests who then complain about amenities that were never offered are amongst the most annoying.
I can see from the response your last host to your review of her that you complained to her about a lack of breakfast. I really hope you did not rate her down for this because I couldn't see breakfast mentioned anywhere on her listing, just essentials, i.e. oil, salt, pepper. So, why is she having to apologise to you for not supplying fruit and cereal?
Do you think that if the majority of guests expected/demanded bread, butter, preserves cornflakes that these would not be standard at most airbnbs? The fact is that people have different preferences for breakfast, some would rather eat out and others don't eat breakfast at all. It totally depends on your market. I do not advertise breakfast, just tea, coffee, sugar etc. but I do in reality supply more, including breakfast cereals. Perhaps one in a hundred guests eat some of the cereal. I stopped providing fruit because most of it ended up in the bin. I'm really not a fan of food waste and will do what I can to prevent it. That's a moral choice.
Saying that Airbnb should tell all hosts to provide breakfast is nonsensical. You are assuming what you want is what everyone else wants, but that is simply not the case. You have the right to choose a listing that suits you. You do not have the right to take away others' right to choose for themselves.
